CD-ROM Driver HL-DT-ST DVDRAM GSA-4084N

[Chris Hinkley]

I tried the solutions posed in this post, including the HKEY mods, and remove / reinstall drive, etc. All attempts were unsuccessful until I found this alternate post:

...which points to this original MS post:

The MS post includes the HKEY fix, but it also includes a link to the MS FIXIT utility. It was the utility that finally did it for me. MS finally scores one back, I suppose...

The Regedit process is simple. I had to call tech support like Monika... Goto "run" in windows (vista/xp) then type "regedit". Once the program is loaded, look at the attachment I have provided. Open the folders shown and delete the "upperfilter" and the "lowerfilter" items in folder named
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

These items will show up in the right hand side. In the example/attachment I have provided, I have already deleted these items. This porcess will fix the driver / failure to load / failure to start problem / error with this DVD Player.

Thank you for posting this info.  I deleted the upper and lower filters from the folder displayed in the attachment.  After I did this, I had to uninstall the DVD drive in the Device Manager which followed me Scanning for Hardware Changes which immediately got the DVD drive working again.  I really appreciate the info.
