Just another app that works excellently with the 770. DVD Catalyst is a Windows XP program that will convert a DVD to 770 format. Another thing to do whilst you are in that vast wasteland that has no Wifi!!

I have it, it works nicely, and the new release 2.0 is out.
It's not only for DVDs, it also accepts files as input. Nice to combine that with democracy player (http://www.getdemocracy.com), and then grab the (high-resolution) files from the democracyplayer directory, and convert them to 770-compatible files.
You can download the new version if you purchased the old one, through the vendor's page.
