Created a DVD. It plays fine on my Toshiba carousel hooked up to the house TV and plays fine on my VHS/DVD combo hooked up to my PC. However, it will not play on the DVD drive in my PC. All programs I tried to access it with says it was an unsupported format. Also when I went to Windows Explorer to see the contents, WXP told me the drive was inaccessible (sp?). The drive works fine. I put a professionally created DVD in it and it played fine. What's up?
