Stacey,

You guys are professional videophiles. You know all the inner workings of DVD players and understand the technology unlike 99.9% of consumers. You understand why some DVD players de-interlace better than others, why buffering systems can come close to eliminating layer changes, and what constitutes a "soft picture."

But for the average consumer and I would venture to say the average hobbyist...issues like the "chroma bug" are a non-issue. Sure, it is evident to the pros...and you spend a ton of time reviewing units and seeking out errors. But for those of us that watch and listen to media in our home, how can this be considered such a significant problem? It seems everything is a give and take. Players with the chroma issue can de-interlace better than players without the issue...etc. etc. There is no perfect DVD player yet.

Stereophile gives the Denon 2800 and the Sony 9000ES an "A" rating on their recommended components. Why would someone as established in the reviewing industry give this kind of rating to a DVD player? Because even they are not infected by the chroma bug. I just don't understand the fanfare that this issue receives...and only in the on-line community. You never hear people talking about it except in the most knowledgable circles. Does this really constitute an "issue?"

I never said it was! As I have said before, I intend to critically look at a large number of players (including the RP91 and RP56) before making a decision. I will say that build quality is important to me, becuase I want something that will last as long as I want it too. Heck, an Ayre bought today will probably still be working after I'm dead! :) I also understand that I can't afford the reference Ayre player. So what I am looking for is as close to reference as I can get for $3000 or less (much less maybe) with exceptional CD sound quality and build/durability characteristics.
Don, you probably know more about the chroma issue than any person alive. I applaud your work!

Eric, you quote may too much. :)
I don't know about the 8000's audio or it's chroma upsampling design error status, however.
It does proper chroma upsampling. It starts of life as a Panasonic RP91. It actually has two sets of progressive outputs. One using Genesis with aspect ratio and one using Sage.

I am bothered by the fact that Stereophile can give an ‘A’ grade to the Denon 2800 because I do not think the picture is ‘A’ quality. Im not sure what these ‘professional’ reviewers are seeing, but the 2800 produces a soft picture with a very bad case of the chroma bug. Yes, the de-interlacing is top notch, but this does not make up the other picture shortcomings.

I also take issue with the Sony 9000 receiving an ‘A’ for video quality because this player exhibits the chroma bug to a lesser extent than the 2800. It also does not have great de-interlacing and it has visible ringing (at least the earlier versions). My point is that I do not pay attention to these ‘professional’ reviews because I rarely if ever hear anything negative about any player. I am only worried about video quality when I buy a dvd player. A good build never hurts, but I do not see this as a positive influence on picture quality because the RP-91 which has a ‘cheaper’ build produces one of the best overall pictures I have seen.

That said, different people have different expectations and things that bother them. Certain people are susceptible to combing while others notice the chroma bug. On a personal level people can buy which they prefer, but on a technical level these are both major issues.

Eric:

You may not notice these issues on your 61” Sony HDTV, but trust me on this one no matter which player you buy you will surely notice more anomalies in the picture on a >100” screen when you move to front projection. The smallest anomalies are sometimes not noticeable on a smaller screen size, but I have seen things using my Cinema 13-HD that I never saw when I was using my Mitsubishi 65905 and 73907. Front projection brings the best quality picture with a great transfer, but with a poor transfer watch out.

The good thing is that we all may disagree on which player is the ‘best’ or which dvd player issue is the most annoying, but as you progress to front projection you will start to become more picky and notice things that you havent noticed before. That’s the beauty of this board. I remember the day when I had my 32” Sony XBR connected via component video to my Sony 7000 DVD player. I thought I had achieved the ultimate picture, but little did I know that was just the beginning… The knowledge gained on a forum like this is much greater than any professional magazine review.

One of the problems with a review is the display device. Each display device has its own set of issues and may not be honest with the video coming in. A video scope is a must if you want to review a video product. It is the only way to remove everything else from the equation. I only know of a couple of reviewers who have such gear.

A direct view TV, for example, makes a video review difficult. The shadow mask in the TV will mask detail and cause its own set of Moire artifacts. A digital display will also have issues with sharp edge transitions and improper video levels. We see clipped video when a DVD player outputs >714 mV. They simply do not have the necessary headroom. When this happens, you don't really know where the problem is and can make false assumptions.

As far as video performance. I like to break that down into several sub parts.

1 - MPEG decoding (Chroma upsampling, iDCT, etc.)

2 - Basic video (freq response, timing, noise, voltage levels, etc.)

3 - Deinterlacing (film, video, bad edits, etc.)

Diagonal of course :) The only other bad thing with a screen that big is that I cant see my little 27 inch tv in my bedroom.

The best thing you can do is to build a list of what you do and do not want in a player.

Here is what I want in order of importance:
  1. Best progressive scan PQ in my price range ($3000) prefer the SilIm over Sage but must be one or the other
  2. Best Interlaced PQ in my price range
  3. Best CD audio quality in my price range
  4. FAST layer changes & quick maneuverability in general
  5. Flexable ouput configuration
  6. Built like a tank
  7. Upgradability would be nice


Here is what I don't want (in no particular order)

  • DVD-A or SACD (if possible - why pay for something I'm not going to use?)
  • Tos-Link only audio output
  • Multiple Disc Changer: Don't want it, don't need it

"A video scope is a must if you want to review a video product. It is the only way to remove everything else from the equation."
If it takes a video scope to "see" or measure these anomilies, why is it a problem? I can understand if these issues plague everyday viewing, and I appreciate the fact that there are people like you kicking the manufacturers in the butt to provide fixes. Maybe I'm gullible, but there must be a reason that the 9000 costs $3k. Is the rest of the video "that good" or could it ever be considered so with the "chroma bug?"
How about redbook playback? Is it a sonic leader in the "DVD-A arena?" You mentioned the quickness of chapter changing and navigation (the 2800 also has lightning quick navigation, so this isn't an innovation at this point). You also mentioned someone else is doing the review of this player, so I'll quit prodding:) I'm just very curious why in the hell Denon would release a POS and charge $3k for it. I refer to it as a POS because according to your reasoning, this is unnacceptable at this point in the DVD game.
I am also curious as to why the RP-56 is a better choice than the Camelot??? Were you serious?

sorry - got lost in the debate. Want to get back to Michael - how is the 9000 compared to your panasonic RP91?

For those who feel CD playback is important and are willing to spend $3000 for DVD and CD playback, I like the idea of spending $200 for the Panasonic DVD-RP56, which is known to show no chroma upsampling error, and $2800 on a CD player (or SACD player). There is a very good chance that a $2800 CD player will best the Denon DVD-9000 playing CDs. If you want SACD, get the Sony SCD-1 for $2800. It doesn't do multi-channel SACD, but it is one hell of a CD player, with stereo SACD thrown in for free. The Panasonic 'RP56 and Sony SCD-1 would make an excellent combo for $3000. For $2800, there are other first-rate CD players to consider besides the SCD-1. An example is the Cary CD-303/200.

The Camelot is a Panny A110 DVD player with a Silicon Image board in it. The Silicon Image board was a stock reference board. The RP56 is a newer Panasonic player with a Sage board. I don't care about CD playback because I have another DVD player for that. The toslink is just fine on DD.

It does not take a scope to see the anomilies, I am stating that a reviewer should use a scope to evalute a player. If you see an anomolie on screen, you have no idea if it is the player or the display or an interaction between the two because of voltage levels. This is the same reason test discs should be used. A test disc is designed to stress out the system.
I will concure that a scope will reveal more than you can see. However, you will never see more than a scope can reveal. i.e. your eyes are not as good as a scope.
I have been busy working on better ratings. i.e. what is considered ok, good, very good, and excellent. I see many ways in which the progressive shootout can be better for everyone. I want to address peoples complaints about it. We have lots of great ideas, it just takes time to perfect them. In the meantime I don't want to share because I don't want to give the other guys a headstart. ;)

That is what I do. I currently use an RP56 for video and another for DVD-A and CD. As soon as the chroma bug is fixed in the other player, I will use it for video playback.
I don't think the RP56 is the best player ever built. (I see lots of room for improvement, but it is $200!) :) I think the RP91 has better video quality, but deinterlacing artifacts simply bother me when I know that they don't have to be there. One comb in a film is one too many.

Actually, the build quality of Panasonic's budget player impresses me greatly. Tap the chassis, and you will find these players to be rather sturdy. Much more so than comparably priced Sony, Pioneer, and JVC players that one typically sees. The drawer mechanism is smooth as well. The drawer doesn't wiggle from side to side when it first starts to close. Many budget models do this, and it irks me to no end. The Pansonic DVD-RA60 interlaced DVD-Audio player also shows excellent build quality for $200. Just my $0.02.

I actually would settle for video reviewers who understand what all the test patterns on Avia are for, and who actually used them to do their reviews. I've read reviews in major magazines that make it clear that the reviewer doesn't "get" video at all.
The first sign of a lame, content-free review is the words "I watched the [something] scene from [reference-quality-transfer], and the colors and tones were breathtaking." First off, there is essentially NOTHING you can learn about a DVD player by watching a reference quality transfer. I don't mean that as hyperbole, I mean literally nothing. Secondly, the colors don't change from DVD player to DVD player. I have yet to see a player that was so far off in color accuracy that a simple Avia calibration wouldn't set it right. (If there is one, Stacey will probably jump in here and set me straight, but it can't be more than one or two).
So as soon as you read a review where the reviewer compares the colors (or worse, the "color accuracy") of two players, you know they don't know a damn thing about how video works, how DVD players work, or how to compare two DVD players. You might as well skip the rest of the review, because there ain't no "there" there. There are lots of similar crap in the reviews in all of the major magazines, and it frankly drives me batty. (You can't tell, can you? :) )
There's something in electronic equipment reviewing I call "restaurant reviewer syndrome." This is where the writer doesn't try to understand the equipment or technology at all, but just tries to capture in words the "essential experience" of viewing or listening. With restaurants, where the experiences are so wildly varied, and there are few, if any, objective criteria, this makes some sense. But in audio and video, the experience of watching Fifth Element on one DVD player is almost exactly like watching it on another DVD player. The reviewer is not going to tease out the essential differences just by sitting and watching and taking notes. In addition, unlike restaurants, there are a lot of objective criteria in electronics. Most video and audio reviewers don't seem to know what they are.
And to say that these objective criteria are unimportant to the average viewer is essentially to point out that the average viewer isn't very critical. Well, duh. The people who read the specialist magazines, or post here, are not the average viewers.
Most of the problems I see with DVD players are easily visible with just the test patterns on Avia, and many of them are easy to see on regular film material once you know what to look for. The chroma bug, for example, cannot be seen on a scope - you have to use your eyes. Y/C delay can be measured most accurately with a scope, but you can use the pattern in Avia to get a good first pass. Measuring frequency response requires a scope, but you can tell a lot just with the resolution and sharpness patterns.
And I have to admit, I'm really pretty shocked at some people's pooh-poohing of the chroma bug. This is an actual bug in these MPEG decoders, folks. It's easy to see on lots and lots of material, unlike, say, a few extra dB of noise or small dips in the frequency response. I've gone to people's houses and pointed it out to them, and every one of them has had no trouble seeing it, and has been amazed that they never noticed it before. The last guy I showed it to went out and bought a new DVD player the next day. He had been enjoying his DVD player for years. And I ruined it for him. Yet, he was happy to increase his knowledge and improve his picture, not mad at me because I was distracting him with trivialities. If only everyone were so open to learning.
An analogy can be made between the chroma bug and Y/C delay. They are both easily visible if you know what to look for (unless you sit 15 feet away from a 27" set), they both are serious video flaws, and yet lots of people blithely watch movies every night on a player that has the problem. Does this mean the problem isn't important? That it shouldn't be brought to people's attention? What is wrong with trying to take people's understanding of video quality to the next level?
-sigh-
Sorry, rant over. Just had to get a few things off my chest.
Best,
Don

Don,

What is the chroma bug?? I know what a chroma upsampling design error is ...... but for some reason my eyes can't read or my ears can't hear or my brain doesn't understand what a "chroma bug" is!! (We call the crap we get in software "bugs" and have lived with it/them for years and keep buying updated revisions of the software to correct the bugs that the OEM should have corrected for us for free, so a software "bug" is accepted by us all as an OK thing to buy over and over again. Don't trivialize the chroma issue by only calling it a "bug". The doggone MPEG decoder and/or the code controlling it was designed wrong.)

I disagree with you about learning nothing from watching a reference quality DVD. If a person knows that a DVD is "reference" and one player does have the following and another player doesn't have the follwoing - then you know the player with the following has problems in at least these areas:

- edge enhancement (from probable bandwidth peaking)

- soft image (from probable bandwidth rolloff)

- twinkling (from maybe non-linear Y/C amplitude enhancement set too high or designed poorly in players that have this)

- red flickering (from CCS being all the time ON in the FLI2200 when perhaps it should have been default designed as OFF)

- video noise (from all sorts of possible stuff being designed poorly in the player that is affecting the analog video channels)

- blacks not right from the player IRE bias point of 0 and/or 7.5 not being set right in the design

- layer changes being way too long

The above is only a partial list that a reference DVD could not mask. In fact, seems like a reference DVD is what you want for seeing the above stuff wrong in a DVD player.

What's tough about using a reference DVD is you must be very critical and picky about what you're watching when you're using it because of a reference DVD's very fine discrimination capablity.

Phil,
I see your point about the chroma bug, but I still think "bug" is a better term, because "design error" doesn't have the same punch. If I could find a way to say "bonehead mistake" with fewer syllables, I would. :)
I need to amend my statement about there being nothing you can learn from a reference-quality DVD. What I meant is that there's nothing you can learn from watching one of the top movie transfers they always use in reviews (Fifth Element, Starship Troopers, etc.) that you wouldn't see better and more accurately with a test disc like Avia or a scope, or in some cases a specific scene that highlights a specific problem. What I'm against is the "reference movie" or "reference scene" that allows you to check the whole player performance at one go. There is no such movie or scene.
Taking your list, for example:
- edge enhancement (from probable bandwidth peaking)
This is much easier to see in Avia. Most movies don't have enough high-frequency information to really stress the analog output of a DVD player.
- soft image (from probable bandwidth rolloff)
Also easier to see in Avia, and even better to check with a scope.
- twinkling (from maybe non-linear Y/C amplitude enhancement set too high or designed poorly in players that have this)
I'm not familiar with this problem. What's a player that has this and what does it look like?
- red flickering (from CCS being all the time ON in the FLI2200 when perhaps it should have been default designed as OFF)
Specific test scenes are best here, such as Toy Story chap. 4, though there are Avia tests that will also show it.
- video noise (from all sorts of possible stuff being designed poorly in the player that is affecting the analog video channels)
If you can see video noise by watching a movie, you have better eyes than I. A video analyzer is the appropriate tool here.
- blacks not right from the player IRE bias point of 0 and/or 7.5 not being set right in the design
You need Avia to check this, or a scope. Only if it's waaaaaay out of spec would you see this with a movie.
- layer changes being way too long
If you want to check this, you should go to a disc with a known layer change time and actually check the layer change with a timer. We use WHQL, because it's easy to get to the layer change, but you could use anything.
My point is that it is important to know what issues you're looking for, and what material will help you check that issue and in some cases measure its magnitude. Sure, some video quirks will jump out at you if you put in a movie, but in most cases, it just makes errors harder to see. The whole point of a test pattern is to focus attention on a single issue, and make that issue stand out in sharp relief. Movies muddy the issues, make some issues masquerade as other issues, and generally add noise to the whole evaluation process.
DVD players are not best evaluated by watching movies. If the individual component and quality measurements check out, the movies will look good as a consequence.

Eric,

How about the Onkyo DV-S939?

Although it may not fit the "Sage/SilIm" request...I think Onkyo is a refitted Toshiba.

Gurus?? Any thoughts on Onkyo?

Or maybe Rotel's RDV-1080...which has the JVC Mediamatics chip...no chroma bug there...

Eric.
