Reply #9: depends on your TV, and the movie in question

[gmoney]

If you have an HDTV, you should see a real difference, but probably also on a regular TV.

You could buy/rent the Blu-Ray of a movie you already have on DVD for comparison purposes. Some Blu-Rays titles are packaged with a regular DVD, such as Coraline, and The Graduate, for easy comparison.

The Blu-Ray player will probably also "upsample" your regular DVDs for some extra sharpness. Also, I've found the Blu-Ray player can overcome the scratches on DVDs from the library or video store that my regular DVD player (or laptop) can't play.

I bought "The Fifth Element" on Blu-Ray, but I'm sort of saving that for when I upgrade my TV to HD.
