I just received the cable today and it worked perfectly. The directions said to put the iBook to sleep, plug the cable into the TV and the iBook, awake the iBook. I ran a DVD, iPhoto and a slide show with new software "Fotomagico", all worked great. Haven't tried iMovie yet, I'm a Fotomagico fan. I have a new iBook, Apple suggested this cable for TV showing. Delivery was great too!
 

We found ourselves in a hotel, wanting to play dvds on the tv (not the little 12" iBook screen) so everyone could watch. I called every video store nearby to see if we could rent a dvd player, but no luck. So I ordered this cable and it arrived the next day. We opened it, plugged it in, rebooted the ibook, turned on the tv, and popped in a dvd. Voila - instant dvd player! Now if only I'd gotten a remote control for the iBook, we'd have it made! No software was required, no driver, not even the VGA adapter that came with the laptop. The cable worked great, and at 10ft was long enough to position the computer on a nearby table while plugged in. This is very handy as a single cable for porting out sound & video, and is great for showing family slide shows as well watching dvds. On the negative side, for portability on trips it was a bit heavier and bulkier than I would have liked. And as a dvd player, it was distracting that the computer screen duplicated the tv. We ened up turning the iBook away from the tv and closing the lid half way. Make sure you check that this cable is compatible with your laptop model. The Monster Cable website says that it isn't compatible with the iBooks that have the RGB video port. Or something like that.
