I have the DVD Joe Satriani: Satriani Live! I watched both discs on my Dell Laptop with no problems. When I tried playing it on my Dell desktop, only the second disc worked. When I put the first disc in, and double click it in My Computer, it says: Windows cannot read from this disk. The disc might be corrupted, or it could be using a format that is not compatible with Windows. I know it isn't corrupt because it works on my laptop. What is wrong?
