DVD Burner will not read or write IBM

I went from XP to Vista, and got this problem. It would work in my XP went to Vista, and it didn't work. I pulled the drive from one T-42 and put it in another one and it did the same thing. I have checked the firmware, and it is current.

Do I just have a fried drive?

I have Nero 8 installed on it.

It will burn CD's just not DVD's.

It shows up in my computer as a DVD RW drive.
