CD/DVD burner fried?? Hi all, My CD/DVD burner wont burn anymore. It still reads and plays discs no problem, however when using NERO or windows Media Player to try and burn a disc it gives errors before even starting. NERO error : 'focus or tracking error' I hardly use the burner. Question is whether this is a Hardware problem and I need a new player/burner or possibly a software problem as my computer has so much crap on it, including multiple player/burner programs? Thank you in advance.
