Vurbano, there are way too many posts on this issue for you to play innocent here. Yelling FUD does not make this little fact go away.
Commentary: Combo Discs - What Went Wrong? | High-Def Digest
Excerpt: "Worse than that, the damn discs don't even work half the time! Just the other night, I sat down to watch my recently-purchased HD DVD copy of '300' on my Toshiba HD-XA2 player, and I only made it 45 minutes before the stupid thing froze up and ceased playback. No matter how many times I try to restart the movie, the disc will not play beyond Chapter 14. This is an extremely high-profile release; in fact, it's currently the best-selling title on either the HD DVD or Blu-ray formats, and the disc won't function in a top-of-the-line HD DVD player! Who wants to put up with nonsense like that? I certainly don't.
Let's not kid ourselves that this is an isolated defective disc or a one-time anomaly. Complaints about playback problems on '300' are widespread, and similar compatibility issues have plagued earlier Combo releases such as 'Children of Men', 'The Good Shepherd', 'Happy Feet', 'Superman Returns', and 'The Matrix Reloaded' (copies from the expensive 'Ultimate Matrix Collection' box set which has the bonus features in DVD format on the flip-side of the disc). Some of these will only work properly on second-generation HD DVD players but not first-generation models, and some bizarrely just the opposite. Some function fine on Toshiba's players but not on Microsoft's HD DVD add-on accessory for the XBox 360, and others vice versa. Some don't work right on any player at all."
Glad you are not having problems Vurbano, but lots of folks do -- I guess we can consider you lucky!
