I think this is rather risky path we are goiong right now ...
If we could just dencrypt HD or Blu-ray and than just burn this to blank media and pop in into any standalone player (especially Xbox360 or PS3) and it would play just fine then we are in big trouble and all Holywood studios would postpone indefinetly all titles and we could screw up all entire segment of HD-DVD and Blu-ray !
I guess they could put up if just this kind of burned movies on BD-R and HD-DVD media would play in PC Drive and some kind of hacked and compromised software or freeware, but no way to play on standalaones without significant downconversion or degradiation or other kind of conversion stuff ...
