    I had a slight question about RPTV picture quality. I have a Toshiba 46H84 TV that I recently got in a week ago. I hadn't much time to test anything except regular cable (which looks crappy at best) and HDTV on my cable box. The HDTV looks pretty good watching sports and some shows on it. I just had time this past weekend to watch a couple of dvds. I found some to be grainy like The Matrix and Finding Nemo. I tested the same dvds on my roomate's 30" Direct-View Samsung HDTV and it didn't have the same graininess to the picture quality. Both TVs have been calibrated with Avia. I was wondering if this is something that is common with most RPTVs or is it just this model?

    Tuan, that graininess does not sound right, especially with those 2 DVD's. Did you use the same DVD player on your friend's set? If not, try using your DVD player on his set. It may be the DVD player. What input are you using on DVD player? Hopefully, you're using component, and not S-video or composite.

    I forgot that little piece of info. On my tv, I'm using a Panasonic XP-30 DVD player with component cables. I have used this dvd player on my previous set, which was a Sony KV-30HS420 but I don't remember how the dvds came out on that set. My roomate's tv, I'm just using his Sony HTIB System progressive scan dvd player. His dvd player shouldn't be better than mine should it? The set of component cables I'm using however, are from the cable company since I am using a DVI-HDMI for my cable box so I had these left over.

    There is definately something wrong. Finding Nemo especially should look fantastic on your tv. is it just those 2 movies or are they just the bad ones?

    I am using a Toshiba 65H84 and all my DVDs look great. Almost HD quality, and again that is on a 65 inch screen using component input. Don't know what is wrong with your DVD situation.

    I also tried Spiderman 2, Spiderman 2 Superbit, and Resident Evil. They all have that grainy effect.

    Have you check your cables? I have had the same TV for about a week and am using a cheap Sony P-Scan player, and mine looks great. If your HDTV picture looks good your component cables may be bad.

    Even before your try other cables try using those cables on the second component input and see if you have the same problem. It may be a bad set of connections on your set.

    If it's not that, then try using your roommates DVD player.

    If those don't work let us know.

    I tried using my roomate's dvd cables which still came out with the grainy effect. Some scenes look nice but some still are grainy. So far I've tried my PS2 with progressive scan enabled connected with Monster Cables which still had the same effect. The Panasonic I've tried with three different component cables which include the ones from the cable company, my roomate's $40 dollar cables from Best Buy, and the cables that came with my HDTV Xbox adaptor. I just finished testing the Panasonic XP-30 on my roomates tv and the picture quality came out great. I play Xbox games through the component connection so its not taking a hit there. I also tested the component connection using the cable company component cables connected through the cable box and the feed didn't take a hit either but the quality wasn't up to par with the HDMI connection. I don't know what to do now.

    I just got a 52hm84 and some dvds look good others not so good. Nemo did look good though, but I am using a denon 3910 upconverted to 1080i. The problem I am having though is that I get a dithering effect on camera pans or a quick turn of the actors face sometimes and it is distracting. Do you get this with your set? I have read that it is something that just goes with the territory of the hd2+ single chip in these dlp sets. I am thinking of returning my set to get the jvc hd-ila which uses a 3 chip design and eliminates the dithering and rainbows.

    Todd smith - My set isn't a DLP set so I don't know what to say about yours.

    I just realized, could the graininess I am seeing be attributed to SVM? I have the set on preference because I have to calibrate the tv to avia. I saw that when set on movie mode, it had no graininess. I am going to double check on this after the Sunday Stew. Anyone out there can confirm this for me?

    Well I figured out the pq issue. It was both SVM and the viewing distance. TV is superb but I think its a tad too big for my apartment and since I'll be moving again after this semester, I think I'll exchange it for the 30HF84 or go back to the Sony KV-30HS420. Too bad the cost of these TVs are equal to the 46H84.

    SVM is the killer!! Just make sure all picture enhancements are off. XP30 should be great on the TV.

    Well I have my RP82 on my Hitachi 57TWX20B and it's awesome.

    How close are you sitting? I'm sitting 6' away from the same set and not having these problems so it might not be all your set.

    I have the set about 9' away from the farthest couch. That is the position I always sit at.

    I'm about 12-13 feet way from my set. Any closer it begins to look a bit big on the eyes and so forth.
