I have a 8X Emprex DVD burner, WinXP, 1 gig RAM, and tons of free hard drive space. I can copy movie DVDs and burn data CDs without any problems; however, I haven't been able to burn a single data DVD with various DVD burning programs including Nero and Roxio. When I try to burn a data DVD, the program consistently uses 99% of the CPU. Initially, I thought it was just slow so I let it sit for an about an hour but it appeared to have made no progress. I've tried multiple times and this is always the end result.
