Drive Not Reading DVD

I have a NEC ND-3530A. I am burning using Nero Every time I burn a data DVD-R I cannot see any files on the DVD using the same drive that burnt it. I double-click the drive (with the disc in) in Windows Explorer and there is nothing there. I ejected and reinserted still no files showing. I also rebooted and nothing. If I take the same DVD to my laptop with the same OS (XP PRO SP2) the DVD shows the files. What gives?

I had just upgraded the firmware successfully to 104C before posting here still nothing. HELP GUYS!!!

Quite common problem for some NEC drives. For details see
