Yeah, I've ripped DVDs before with DVD Backup, and yes, I was thinking about just the "pure" DVD rips (using DVD Player on the VIDEO_TS directory), not encoding to .avi (takes too long, even on my current G4 1.25 Ghz desktop). 4 hours sounds pretty good though. Not that I'm planning on watching that long necessarily, but I just wanted to know how much more battery I could save by doing that instead of watching off of the DVD drive. Would rather not have to keep the drive spinning for two hours plus.
