I have had many people complain that the DVD player either stinks or doesn't belong in there. Some people even want to prove that it is illegal release....of course it is a illegal release, -all- xbe's are illegally spread as well as all free MPG2 players are. MPEG2 is a copyrighted format where you pay a licence royalty per player, and even tho I have in my company payed over 200k USD for mpeg2 sources and licences, not even I could release a free DVD player that is in software only.
Now, making such a player work on xbox is not an easy task - but somehow JBone made it compile, work and also made it possible to inject into avalaunch. In many ways even the good old dvd-x2 is better, in others XBMC is far better. XBMC is not replacable, that's not our intentions...but DVDx2 doesn't use a dvd players full potential, so we want to create something for the xbox users.
