Agree with others and as CC said, we need to know what Fab application you downloaded. The two folders you described are compliant with standard dvd structure and can be “worked with” no problem. BTW, the AUDIO_TS folder is empty. This is normal and complies to standard dvd structure.
If you don’t have Platinum, you can download and install it. You’ll have the full-featured, retail program with a free trail for 30 days, no strings attached.
Rip the movie with Platinum or with DVDFab HD Decrypter…this is the freeware version. Both apps will rip the movie to your hdd.
Now with DVD to Mobile (also availble as a free trial), simply navigate to the ripped files, and convert them. For Ipod conversions, I’d use MPEG-4 or H.264. You’ll find both profiles availabe in the Moblie app. It’s all pretty straightforward. There are also tutorials available online and on the Fab subforum.
Don’t be afraid to experiment.
As Kerry said, Handbrake is another option for you and is availble as freeware.
