So we agree. :-) > The true test is not movies ... it is sports shot live on 720p or 1080i, > Leno, or the better ABC HDTV sitcoms. Agreed. However, I've made the comparison of the same sports material at 720p and 480p (using the downsampling capabilities of my HD-Tivo), and other sports at 1080i converted to 480p, and while I thought the differences were significant (and how could they not be?), "real" 480p still looked surprisingly good, and certainly much improved over deinterlaced 480i. If I can find the time, I'll do some tests here with 720p compared to 720p->480p->720p. Obviously it'll look worse, but I think many will be surprised at how good 480p can look. If I can find a clip or still I can put on the net, I'll stick the comparison somewhere folks can see it.
