Hi Bill - here is what QuickTime Kirk (an acknowledged expert on these forums) has to say regarding your problem:
"Install this new software and quit and relaunch QT Player (if running).
Open QT Player and then insert your DVD. Quit DVD Player if it starts.
From the "File" menu of the QuickTime Player choose "Open File". Navigate to the DVD and its VIDEO_TS folder and click OK. Your file should now be playing in QuickTIme Player.
QuickTIme Pro can't edit or export this file with audio. It can't be imported into iMovie until it is converted.
Download and install MPEG Streamclip (free).
Open MPEG Streamclip, navigate to your DVD and choose the VIDEO_TS folder. Click OK and it will open in Streamclip.
Choose "Export" and pick DV Stream. Wait for the conversion to finish. It will make a new file (you name it).
Open iMovie and "Import" this new .dv file and make your edits, etc. "
Does that help?
