Hi. Im having trouble burning mp3s from my hard drive onto discs at the minute. Most of the track is fine, but for the first few seconds of each track it seems pretty jumpy and seems to repeat a second or two. I never used to have this problem, its only in the last week or so thats its happened. I was using an NEC 3500 burner, but ive swapped that for an NEC 4551 now, but still get the same results. Any ideas?
