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
DVD players cannot play Bluray discs. The lasers and the data storage are different so no data can be read from a Bluray disc in a DVD drive. That is the case whether or not there is any up-scaling available in the player. Bluray players on the other hand are quite happy to play DVDs as well as Bluray discs.

No. All current 3D disc content is HD and so use Bluray discs. You have to have a 3D Bluray player.

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.
