Hey George, did you by chance have a copy of Roxio or Nero on that laptop that came with the computer? Did you open either one of them? What program did you use to import the video CDGs? The reason I ask is because some of these can mess with your upper and lower filters in the registry. You can delete these and they will automatically reset after a reboot. If you are comfortable editing the registry, here is the procedure.

1. Start Registry Editor (Regedt32.exe).

2. Locate the UpperFilters value under the following key in the registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

3. On the Edit menu, click Delete , and then click OK .

4. Locate the LowerFilters value under the same key in the registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

5. On the Edit menu, click Delete , and then click OK .

6. Quit Registry Editor.

7. After you remove them Restart your computer.

If this drive is working on your XP machine, this is most likely a Vista error or another program error that is not common to both machines. This is the safest and easiest step to start with. Next, I would try deleting the drive and drivers from your system and let Vista re-discover them. You shouldn't need to provide a driver, Vista should take care of it automatically.

Keep us informed on your progress even if MTU fixes this for you. Someone else may benefit from the exchange.
