I just bought a GSA-4166 and it will not recognize or play commercial or blank DVD's, it will play cd's fine.
I updated it to 1,02 firmware (it had the problem out of the box) and it makes no difference.
My computer shows it as a dvd ram drive where it shows my lite on as a dvd-rw drive (I don't think that's a problem).
I'm running MCE SP2.
Anyone have any suggestions?
