I would check that the disc is clean - from what
AnyDVD is reporting is doesn't seem to have any special protection. Might be that the disc is defective or scratched. Might be worth trying to copy and paste the disc to your hard drive - see if works.
Nero CDSpeed will tell you if the disc has any errors.
If all the fails - maybe DVDDecrypter might rip it - then
CloneDVD2 can work is't magic straight from your hard drive.
