do you have limewire?
if not download that. then search mp4 download the movies you want, some might not work.
if you go to google videos, some videos can be downloaded.
or you can go with my route.
download videora, idk where you find it, buts its free. google it or something.
one the home screen of videora, click on the DVD option.
then follow the steps it gives you. it will help you put any DVDs you have on your ipod.
i have like 25 moves on my ipod right now. that i either converted from DVDS or gt off limewire.
