I'm trying to backup scrubs season 4 disk 1, i havn't tried disk 2 or 3 yet. Anyway Dvd shrink can anlyze it but when i press backup it constantly locks up at 2 percent. doesn't give any warnings or errors. just locks up. So i've tried ripping it with dvd decryptor both as an iso and vob folder - both have been succesful - but then when I try to shrink the iso file since it is 8.30 gb's. It always locks up at about 82% giving a cycle redundant error. When I try to backup the vob folder it says there is a problem with a vob folder or dvd shrink doesn't recognize this folder. Anyone have any ideas?
