I have been reading both data and video dvds for the past week on the ibook G3 I just bought off ebay, and all of sudden this morning it won't read a DVD at all. Cds still work fine, but a dvd just makes a sort of faint scratchy noise and then gets spat out after about 5 seconds. What on earth is going on?? It's an iBook g3 800mhz with a cd-rw/dvd-rom combo drive. A cd doesn't make any odd noises whatsoever and reads fine. I've checked under OS 9.2 and the situation is the same. Any help very much appreciated!
