I spent yesterday trying to sort this problem out. I bought a new Burner and swopped cables and was back and forth from the shop. I sorted it out finally even though the guys at the shop said it couldn't be the problem. It turns out the disc i was using were faulty, the guy at the shop got all funny with me and tried the discs himself and he couldn't get it to work either. So he swopped my discs over and now it works fine. Out of pocket because i bought a new burner but i'm happy it works now. So my advice is to try differnet discs. So thanx for the help and i hope that i never get this problem again. Hob.
