First time I have come across this problem.
I tried to copy Wallace and gromit curse of the ware rabbit using anydvd 188.8.131.52 and it came back with the error no video_ts. I also tried DVD decrypter and this wouldn't read the DVD either.
I looked at the disc in windows and it appears empty, I also tried playing it in media player and it wouldn't work either.
Put the DVD in normal DVD player it works fine.
Has anyone copied this DVD? If so how?
