Sis is just too right IMHO... If I could go and have my DVDs swapped into HD versions (hey, I've played for the right to watch the movie, not for owning it, correct? so why should I pay
again?
then I wouldn't think about buying a HD player. But as I'll have to buy every movie, and most likely at a higher price than its DVD version, I'll certainly think twice about it. The difference in image quality might not be important enough to try to sell a large DVD collection and pay a lot of extra money to buy them back again.
Actually, even with new releases, one would have to consider which version to choose if the HD version would cost 2 times as much... Recent DVDs look pretty cool on my HDTV already (okay, it's 'just' a 32 inch LCD and not some 50 inch plasma).
