Yeah the Bluray if not hooked up in the best manner wont show that much better but when it is hooked up right it is quite clear. Also the sound I find is much better. However I went in to buy Gran Tourino(great flick) the other day and even though I do have a Bluray I did not want to spend $30.00 on it so I bought the widescreen DVD instead. Figured I could use that $10.00 dollars I saved to take my daughter and wife to get ice cream(I am not self centered ******* I know hard to belive in this day and age.).Also a BluRay player is supposed to run a DVD better than a DVD player can but I suspect that is marketing bull****.
I thought there was some diffrence in the storage between the two. i know that is why BETA lost out to VHS. BETA gave a better quality picture but it could only fit so much time and it meant that alot of movies required more than one tape while VHS could store much more so as long as the movie was less than something like 2 1/2 hours it could fit on one VHS tape.
This time around with Bluray and HDDVD there was even some studio backing one format or the other.
