Cant get dvd to rip to avi

Hi, just got a copy of dvd fab platinum. I’m trying to rip camcorder dvd’s (video_ts files) to avi to allow me to edit them.

Now, the problem i’m having is that it starts, then get’s to 0.37% and then goes no further. I’ve left it running for a few hours just to see if it would carry on but no joy. Any ideas and does anyone know of the EASIEST software to convert video_ts files to avi??
Cheers in advance.
