Q: DVD Does not function in Windows 7 Pro This thread is locked from future replies

I have the same problem as described in this Article ID: 975270  The DVD drives in my system are inaccessible.  Both show in my computer and can play music CD-ROMs but cannot read or play DVDs.

My drives are LITE-ON DVDRW LH-20A1S.  I attempted the fix outlined in the article but received the message:
   "The power scheme, subgroup or setting specified does not exist. "

Other solutions offered on the web also do not work.  re-letter drive in Disk Management.  Delete UpperFilters/LowerFilters from registry (these subkeys do not exist in my registry.

I have the latest Firmware from Lite-On 9LO9N.

Any solutions????
