So I have a Windows 7 PC running Media Center (home theater situation). I have one of those LG super-everything drives that can play Blu-ray as well as HD DVDs. Most of my movies are Blu-ray but a still have a few goodies on HD DVD and I've been itching to watch one of them. Trouble is I cannot get it to play at all, not even outside of the media center interface.

Any suggestions?

i think your dvd was corrupted pleace chek it outside the pc
