Please give model-specific info on upgrading firmware for the BenQ OEM 1620. I have doen the following: Run WinDWFlash firmware installed: B7T9.cvt and B7T9.rpc1.cvt from the Win98 desktop. This procedure went successfully. Is this the correct procedure and are there other things I need to know? Also, where would be the correct forum for a question on Nero OEM playback? I noticed that Nero audio player was not playing audio at the same levels from both channels.
