My apologies if this is posted in the wrong forum.
I had an issue with my Pioneer DVR-110D DVD burner. In Nero the buffer level was cycling from 10% to 85% and it was taking 30minutes to burn an 8x DVD! Thanks to CDFreaks and a little searching, I found that my issue was my drive was not in Ultra DMA mode. The problem was that I needed change my ribbon cable to an 80pin cable rather than the one that came with my computer case. This immediatly fixed the problem. Now DVD burns in 8min. Thanks again!
