Problem backing up Sopranos season4

[magister66]

Hi all, I am having troubles backing up disc 2 of season 4 of the sopranos, any suggestions. It seems to rip the files fine then comes back with an error copying the disk. have tried xcopy platinum, dvdshrink 3.1 and running anydvd as well. still haven't got it to copy. the other 3 discs copy just fine.
