I have a Lite-On DVD Burner. It is USB 2.0 and is plugged into a non-High Speed USB 2.0 port. I use Memorex DVD-R. My writer can write 8x and my DVDs are 8x but it takes 9 hours to burn 1 DVD. I have a Pentium 42 2.0 GHz proccesor and 1 GB of Ram and 100 GB of free hard drive space. I use Nero 6 OEM Suite that came with my burner. I know it should take only 1 hour. Please help ASAP
