I am having a problem burning to TYG02's at a speed faster than 4X. I have attached a DVD Speed test at 16X. It took over 16 minutes. It seems that no matter what speed I burn at it takes 14 plus minutes. I can burn +R's ok.
While watching the graph as I burned the DVD it looked like it burned to 9X, then there were long pauses every 15 seconds or so, as it worked it way up to 15.5, then dropped to 5X.
DMA on as far as I can tell
