Anyway, I took the DVD home and it burns fine on my PC, no problems !! I did manage to burn a data DVD on her new PC, but why wont it burn this particular disk. Its not copy protected or anything like that. The PC is only a few weeks old.
I tried everything including downloading latest firmware, uninstalling DVD in Device Manager. THis is driving me crazy. On top of this Im getting nowhere with DELL helpdesk. Any Ideas
