SATA DVD RW drive detected as cdrom
Hi,
Win7hp/32b. SATA DVD RW drive is detected as a cdrom drive in my computer (explorer).
I have searched all kind of resolutions and until now no solution. Before I tell what i've done, I have a multiboot configuration. In XP, Vista, and Ubuntu on same pc the drive works correct. If I connect an external usb DVD RW drive, same symptoms. Explorer says CD rom drive. This external drive works also good on my Win7hp/32 laptop. So no cable/connection issue. If I put a DVD video in the drive it is not recognized as such, though I can play it with VLC. But WMP12 does not see a DVD in the drive. Funny is that if I put the DVD in when WMP12 is open, it autoplays and runs in WMP12. Neither I have a burning problem. DVD maker and Roxio do see the drive and I can burn DVD/CD's. See below, I think it is a registry problem and not a driver (cdrom.sys) problem. Somehow the DVD references (filters?) are not working so explorer is not told it is a DVDRW drive. Guessing...

Well at this stage I'm almost opening the window... but I really like to find out what is wrong, but it is taking too long and the wife is getting annoyed... anyone a suggestion for me?
