I use a program called DVD to Pocket PC from
http://www.makayama.com/dvdtopocketpc.html . It works great for me and I can use the Windows media player on my Axim to play the movie. Put the dvd in your pc, open the DVD to Pocket PC program and hit 1 button, wait 5 hours and you're done. I put a dvd in before I go to bed and wake up to another movie for my Axim. :)
