I've become an HD snob - there's only 2 shows that I watch in Standard Def: Dr. Who and Battlestar Galactica. I could watch BG in HD on [link|http://www.universalhd.com/|Universal HD], but they're just now starting the season 3.
Make sure you tell your DVD player that it's on a 16:9 set, otherwise it'll assume 4:3 and discard 1/4th of the picture detail before it sends it to your TV.
