Agreed.The picture quality I get with my standard DVD player and Sony HDTV is pretty close to breathtaking.But not quite as good as some of the stuff you see on,for example,Discovery HD.Some of the nature programs shown in HD are absolutely astounding,IMO.
If the price is right,I may well be willing to spring for that small improvement in picture...particularly if National Geographic starts releasing HD-DVD's.
Keep in mind the Discovery channel was recorded with HD cameras and IMO the movie Business will never go that way because it would look to live to seem like a movie anymore.
The quality I get with my LST-3510A playing DVD with a projector onto 13 feet of wall is far superior to the picture I can get in the actual movies.
