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?
