When I run certain movies through DivX Doctor II I get odd error messages that result in my QuickTime movie being visually corrupt in areas or off synced sound. So I can edit the DivX movies in QuickTime that I rip from DVDs (for backup!!!). I'd like to be able to make certain rips fit onto CDs, and if I can't edit the files.. how can I make them fit w/o splitting it?? Thanks.
