Trying to backup Shrek (the first one) and having a problem: When I open shrink and it starts to analyse it spends about the first 8% on the same couple of frames; (the dragon flying though the clouds. In the preview it appears to just going back and forth. It finally gets out of this 'loop' and analyses the rest of the film. When it comes to encoding however it gets to about 3% and this: DVD shrink encountered an error and cannot continue. Programming error – exception occurred First time I’ve seen it. Any suggestions?
