This is what I am using:
http://xoomer.alice.it/sepaolo/n800vc/

25 fps, optimized for the N800's screen, left default audio settings alone. I just hook up my N800, and select the N800's SDHC as the output folder, and then queue a whole bunch of TV episodes for conversion overnight.

The next morning, it's just disconnect and go

Speaking of which, time to get my Heroes Season 1 encoded for the N800. Been procrastinating too long
