This is a similar problem I had with another movie concerning AnyDVD rip to hard drive and then using DVD Shrink.
Ripped to hard drive ok. Opened DVD Shrink and got an error “cannot read VIDEO_TS.VOB”.
Unlike the last movie where the VIDEO_TS.VOB was not in the ripped folder, this time it was but DVD Shrink could not read it. I checked the original DVD and compared the sizes on the 2 VIDEO_TS.VOB files and they were different sizes. I then copied the VIDEO_TS.VOB from the original and pasted in the ripped folder, overwriting the old one.
This time DVD Shrink processed it fine.
