When and how the movie was made is really illrelevent when it comes to the differences between DVD and blu-ray. Film stock still maintains a rather exceptional level of detail (or resolution), so when the movies is remastered for blu-ray, it’s going to contain a much greater level of detail than you would find in a DVD. The quality is always, unquestionably, better. I’ve been working on some blu-ray projects with Warner Home Video and have spent a lot of time around blu-ray. It’s amazing.

Without hesitation Blu-ray is better… if you have the equipment and viewing environment to exploit the betterness.

For 99% of people, DVD is and will be fine.

Blu-ray is simply a marketing ploy to sucker us into replacing our DVD’s in the same way we did our VHS tapes.

What has been forgotten is that the DVD to Blu-ray step isn’t the big leap that VHS to DVD was.

Blu-ray for sure. Once you go blu u never go back.

Blu ray is way better because of it’s capacity. A blu ray disk holds up to 50 gb of information which is wayyyyyy more that a dvd can. More info passing through the cables, the better the picture and sound quality. (that’s the easy answer anyway)

Blu-ray has the best picture. However, the blu-ray players are from $200-$500 from what I have saw. They do play regular DVD’s but the quality is not as good as an actual blu-ray disk. A blu-ray moive will run you about $30.

blu ray quality is amazingly bettery, it’s like perfect. only drawback is money, the bluray player usually costs more and the actual disk costs more than a DVD disk.
