I just got a DVR-108 today and installed it fine. It reads CDs and DVDs with information on them but when it’s a blank CD-R (Haven’t tried DVD±Rs), It just doesn’t detect it at all. When I double click the drive in My Computer, it says “D:\ is not accessable, incorrect function”. I have updated to the latest firmware but still the same problem. I read around the forums that others are having similiar problems but I couldn’t find a solution anywhere. I tried 3 different types of CD-Rs, 2 branded high quality and 1 of the cheap kind but they all weren’t detected. Anyone that can solve my problem I will be eternally gratefull and will even donate $5 US to there paypal account. Thanks in advance.
