after reading this i had an idea, since hd dvd is backward compatible then is it possible to make games on hd dvd that are backward compatible? I mean like, lets imagine that an hd dvd add on comes for the 360 in the future and developers make hd dvd games for it and those who don't have the add on can still play the games in the regular xbox drive but with sacrifices. Similar to how hd dvd's can play in regular dvd players but without hd.
You might want to check your facts. HD-DVD requires a new laser type, just like dvds did compared to cds. Sure a dvd player can read a cd, but a cd player can't read a dvd. Why.............different laser is needed. Backwards compatiblity means just what it states.........the new technology can use back technology also. To put it simple a HD-DVD player will read DVD's, not a DVD player will read HD-DVD's. The data is much more compressed on an HD-DVD disc and needs the 405nm wavelength blue laser.

DVD uses a 650nm wavelength red laser. A cd uses 780nm wavelength red laser. See the trend yet? As the data becomes more and more compressed on to the same physical size disc, the laser wavelength needs to be smaller.
