i've had this trouble since i bought my set last october and still haven't been able to figure out what's goin on.
I have a samsung hi-def 55" rear projection tv. and i have a denon 910 dvd player. i'm using monster component cables. now, when i have the player set at 480i the pic has more detail, the black is deeper but also the pic is grainier and if the screen is a mostly solid semi-light color, i can see a vertical bar of a lighter shade than the picture somewhere on the screen.
when i have it set to 480p, the pic is smoother but the black is not as dark, detail is lost and the pic actually looks slightly blurry.
can anyone explain this? thanks for any info.

Same with my tv the 480p gives less detail. I just decided it was my crappy dvd player. You on the other hand have a great dvd player. I dont know why its like that. Hm....

I have the Denon 2200 and it look stunning. It's a great DVD player. It will be my last 480p player until HD DVD comes out.
Are you sure that you are choosing the right modes? I have seen a remarkable difference when I switch to 480p over 480i. The 480i looks awful. Way too much red and the flesh tones are off. When I turn back to 480p, the picture is much easier on the eyes and life like.
On the 2200, the 480p is almost simular to 1080i, depending on the transfer of the movie.
HBO aired "Charlie's Angels, Full Throttle" in HD and the night before I watched the same movie on DVD and the 480p looks almost the same as the HD signal.
I don't know the 910 user menu, but on the 2200, you can tweak the colors, brightness, etc, in the DVD player.
The 2200 was one of my best upgrade that I ever did to my setup. It's well worth the price. I also looked at the 910 and was impress of the picture, but when I compared pictures to the 2200, I was sold!!!

Sounds like a TV calibration issue to me...in this case it seems your TV has a better setup in 480i than 480p. Calibrating your TV for proper 480p is in order, I think. 
Mahatma Gandhi, as you know, walked barefoot most of the time, which produced an impressive set of calluses on his feet. He also ate very little, which made him rather frail and with his odd diet, he suffered from bad breath. This made him...a super-callused fragile mystic hexed by halitosis.

Is it possible Samsung's deinterlacer is better than Denon's? *shriek*

I agree with Max. Sounds to me like you need to have your TV calibrated. With the kind of money that you have in your equipment it would be well worth it to have a professional calibrator stop by and set your TV up to ISF standards. The results will blow you away for sure.

If anyone sees a difference in COLOR between 480i and 480p, it is most definetly TV-setup related since COLOR has nothing to do with the different scan rates (as long as both signals are getting to the display device via the same component connections).
Anyway, I remember reading posts like this a year or so ago. If your TV converts incoming 480i to 480p (don't all HDTV's do this?), you ARE watching 480p! (note- some TV's convert in-coming 480i to 960i or 1080i) The difference between a TV's line-doubler and a DVD player's de-interlacer can often be quite subtle since they are bascially doing the same thing. You see, DVD's aren't encoded as progressive anyway. They are interlaced. If you read the old review at hometheaterhifi.com of a Pioneer Elite HDTV, you'll see they actually PREFERRED watching 480i converted to 480p by the Pioneer HDTV vs. 480p from the DVD player simply because the TV's line doubler was THAT GOOD!
My suggestion is to view resolution images on a test/setup DVD like AVIA or Video Essentials both ways (input as > 480i/480p) on your TV. Even if your TV uses a "universal" picture preference setting vs. individual settings for each input, you could have hidden 'service mode' settings that are set differently for each scan rate input. Who knows, your 480i input may be set too sharp (which could make it look 'grainy'), rather than your 480p input being set too soft, which may account for the difference.

yes, my tv does convert the signal to 480p, but i find it strange that the samsung deinterlacer is better than the denon, knowaddamean? and there's also the issue of the wierd vertical bar in 480i mode. now, the colors don't change. it's more like they're not as vibrant in 480p. lastly, where do i look for a professional tv calibrator?
