I have had nothing but problems with this disc. I was finally able to make a backup of the entire disc, but I still can't get the movie from there. The special features come out fine, but the movie always starts having trouble around the 25GB mark and I get this error repeatedly.

I read an older post where someone else had issues with the disc, but I believe they submitted their dump file and got it to work.
