Hi - I have the 165H6S running on WinXP pro, secondary master. Firmware has been updated to HS0E. Region 1 and no region changes have been made.
The device was working fine for a few weeks. Today I use it after not using the drive for 4 weeks, however, it will not read any commercial/retail DVD’s. It thinks the drive bay is empty. It reads previously copied DVDs and all CDs without problems, however, any retail DVD I put into the drive fails to recognize.
