Vista Upgrade: DVD Driver Problems FIX - Roxio DLA

The gods too are fond of a joke. - Aristotle

Recently I upgraded XP Pro to Windows Vista Ultimate. It wasn't until sometime later that I found I had lost my DVD drive. The driver appeared in Device Manager but it had that familiar yellow exclamation mark indicating a problem loading the driver.

After a bit of searching, I discovered that the culprit was Roxio CD/DVD software (e.g., "DLACDBHM.SYS" et. al.) which is not Vista - compatible, and thus blocks correct loading of the built in Vista CD/DVD drivers.

The FIX:

First step, in C:\Windows\System32 you need to find the DLA folder and delete it. That's their "Stuff". If you want to get sophisticated, you can search the registry for all keys that point to any of these .sys drivers and remove the entries.

Next, run this Registry Fix script courtesy of Doug Knox:

Set WshShell = Nothing

Message = Message & "You may need to reboot your computer to see the change."

MsgBox Message, 4096,"Finished!"

The above script should be saved as "xp_cs_dvd_fix.vbs" and you can execute it out of Windows Explorer by double-clicking. This is a pretty old script but the most important thing it does is to remove the "UpperFilters" and "LowerFilters" entries.

Note: the above does not remove Roxio DLA - which is incompatible with Vista. Here are full instructions for that:
