Ok, so, I picked up a 20 inch iMac g5 today, and set it up right away when I got home. I stuck in a DVD, it played, I was thrilled, quit the program, ejected the disk, and went about installing programs. I just tried to put the DVD back in, and the slot loading mechanism wont "grab" and take in the disk. i can push it nearly all the way in, but the imac never takes it, it just sits there, nearly all the way in. I did a restart, and same thing. Anyone else see/hear about this? or is it just me? any help appreciated.
