I know it's 8x, which is why I think I definitely did something wrong. I used Roxio Toast to burn 6 episodes of the office on a single layer DVD (about 2 hours and 15 minutes). It took over three hours to do this. I'm not a DVD expert, but on my old PC with a 16x drive it wouldn't take more than 20 minutes. Did I do something wrong? Is the DVD burner really this slow? Another reason I think I did something wrong was because I could not tell that the DVD was burning. It was completely SILENT, but my CPU usage was at 85%+ for all three hours. Toast's settings said burn at maximum possible speed. I'm using the 3.06 new iMac.
