I have a new Sony Bravia 1920X1080 47”, with a new Sony Blu Ray. I can play regular (non HD or Blu Ray) old DVDs and they look Hi Def on this tv, (NL’s Christmas Vaca). Apparently it ‘upconverts’ or something like that. I should also mention that we had a Blu Ray DVD of the original Star Trek tv show and it looked like old tv.
That's just what it does,"upconverts".I,too,have a good quality HDTV and player and the well mastered DVDs look noticeably better than they do otherwise.
