First - In device manager, hit view --> show hidden devices. Are there any hidden/non-plug and play devices that aren't functioning properly? And what is the complete error message in device status on the DVD drive?
Then I found this http://pcsupport.about.com/od/findbyerr ... -error.htm
I tried #6 "Delete the UpperFilters and LowerFilters values in the registry"
and it WORKED!!!!!!
Thanks for the posts and I hope this may help someone else in the future.
