Okay, here's the big long story: I started out with a PM G4 Digital Audio 533 MHz, thinking it would make for a decent machine that I could upgrade as needed. So I installed an NEC AD-3550 DVD burner, and installed 10.3.9. The drive's burning capabilities was not supported, so recently, I just bought and installed 10.4.6. Now, the burning capabilities are supported, but when I insert a DVD or CD, it is RARELY recognized and mounted. The same goes with when I plug in my iPod shuffle, which is not mounted in iTunes or on the desktop. Also, Software Update gets about 1/4 of the way in checking for new updates, and hasn't made any progress in the 4 1/2 hours that I left it run this morning. As for viewing options, I have the box checked for removable media to be mounted.
