Essentially I'm trying to rip & convert DVD video to play on my iRiver PMP120 (Div-X codec).. the problem I'm having is that the files are not ripping or converting  and are unplayable, even using the Div-X player. I've updated to the latest codec (6.5) and still no luck.
 
Please advise what I can do, or what information you need to help resolve this issue
 
Many thanks
