I've just begun trying to do that on my Pandigital Novel. I used DVD Fab to "rip" the source DVD, then used Handbrake to create an MP4 (or M4V) version. The result was copied to the external SD. I've found that I need to be sure that the Codec is MP4 to be able to see anything. It works, but the quality isn't very good. I've got to do some more playing with it.
