Blu-Rays are used only for high definition. Blu-Rays hold up 5 times more data than a DVD can hold. Blu-Rays have capabilities that are way ahead of DVDs, such as accessing the bonus material while watching the movie
Beacaus bluray is newer and they think everybody has a bluray player... eventually it will come on dvd.
A DVD player cannot play a BluRay disc. A BluRay player can play both BluRay discs and DVDs.
No
Could be nothing more than the Bluray DVD's that you're watching aren't encoded in 5.1 surround.
A DVD player is a better decision than a BluRay player based on price alone. This type of player is cheaper. A BluRay player may be a better idea because it can also play DVDs and has more advanced features.
No. DVD quality will be displayed whether the player is a DVD player or a Bluray player. DVDs won't be the same quality as a Bluray disc of course.
Yes
To play a high definition DVD, you need a high definition DVD player. There are two types available currently. HD DVD, developed by Toshiba is one and BluRay, developed by Sony is the other. They are not compatible, so an HD DVD will not play on a BluRay player and a BluRay disc will not play on an HD DVD player. BluRay looks like it is the winner in the format war between the two companies over the last years so it is likely that Toshiba's format will disappear in the coming months. Note that HD DVD can refer to the Toshiba format but it can also refer to high definition DVDs in general.
HD DVD and Bluray were competing high definition disc formats. In 2009 HD DVD was withdrawn from sale as it became apparent that Bluray had won the HD disc battle. The two formats are not compatible so HD DVDs can only be played on an HD DVD player.
No it cannot you need a ps3 or a bluray player
No. All current 3D disc content is HD and so use Bluray discs. You have to have a 3D Bluray player.
the only difference is that the cut scenes look a little better on PS3 due to 360 having to compress them to fit on a dvd vs a bluray.
