I think this might be more appropriate to a different forum, if so a
pointer would be appreciated.

I have a laptop (ca. 2003, Pentium 4, Win/XP) with a DVD/recordable CD
drive combo.

The Drive plays DVD movies just fine. Just recently I received a DVD
with file content.

When I put this DVD into my drive, it is as if there is nothing in the
drive. I can place the DVD into the DVD drive of an older computer I
have and I can get the DVD to run and display its contents.

I can't even begin to figure out how to troubleshoot this problem. Any
hints?

Thanks
