As a prospective iBook buyer, I was curious if anyone has ever tried watching DVD movies that were ripped to their hard drive. On CNET's review of the iBook G4/800 they reported that watching a DVD full screen with sound on will drain the battery in about 3.5 hours. If I rip a DVD to my hard drive and play it off of there (full screen w/sound on) will I get appreciably more battery life? I assume that keeping the DVD drive spinning accounts for a lot of battery usage.

If anyone has any ideas let me know, thanks! This isn't a deal-breaker by any means, I was just curious if anyone had tried this and what their results were.

you talking about the 700mb .avi rips? or an actual dvd disk image with the movie on it. ive done both, but i dont really watch the time.

my battery on my 14" will play a high quality .avi (divx doctored of course) for something like 4 hours depending on how i do with the backlight.

You can watch DVD's off the hard drive no problem. The program to do the ripping is DVD Backup.

However, I don't recall it saving me all that much power. Plus, the discs are usually around 7-8 GB each, which means you only can save a few DVDs to disc before you fill up the hard drive. I don't think re-encoding to Divx or whatever is worth it, because the re-encodes take forever and the quality is worse (and you lose all the menus etc.).

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.
