I downloaded and installed the new Official 5.1 drivers, to see if they worked any better than the original version I got with the card. The driver install seemed to work quite well, but after rebooting I noticed that my CDRW drive was not showing a drive letter under windows.The drive still shows up under Device Manager (with its former drive letter assignment in properties); but a selection for the drive does not appear in explorer, nor in Easy CD Creator to recognize the drive. The DVD drive still shows up just fine. I have tracked the problem to the driver install itself, and not the additional AudioHQ and Mixer apps. If I uninstall the drivers and reboot, I get the drive letter assignment back
