I've been using DVD Shrink 3.1 for some time now with great success backing up my DVDs, but just stumbled on a problem. I tried to re author just the film portion of "Escape from Witch Mountain" and DVD shrink says it's too big. The film is only an hour and 37 minutes long. The bar has 4,464 MB in green, then has a small red section at 4,830 MB. This is with both the audio commentary and english subtitles deselected. Can't figure out why it's doing this.
