I have a Pioneer 107D and have been using it with no problems until yesterday. Windows explorer starting showing as a CD Drive when a dvd disc was inserted. When I tried to burn an image in Nero it said it expected a CD-RW disc not dvd. The burner is listed ok in device manager; I have upgraded the firm ware; the system aspi files were incorrect but are ok now. Any help would be appreciated. I am using XP.
