I have been having problems with my new Sony External DVD burner. I can burn data but can not back up DVD movies. I have tried different software and media. Sony says that my processor is the issue. I currently have a 1.6 Pentium 4. I have enough hard drive space and RAM....Can I successfully burn a DVD movie with a 1.6 GHZ processor or is Sony trying to get me to upgrade? Is there anyone here who uses a 1.6 and has no problems? Thanks for your help!
