i got a 52x24x52 cd burner and its a pos! it never burns nething completely! it keps on stopping and when i set a write speed and burns it at a different speed! it will burn at 1x sumtimes, and then 52x sumtimes, and all the numbers in between, but it usually stays at 10x! and i always get errors and it stops in the middle, plus the green light is always on when there is a disc in it, and it occasionally makes strange sounds
