Here's the problem. I have a memorex 48x24x 2448aj burner that won't burn. I've tried different media, different speeds, different software, all with no luck. When I start to record, my system just hangs, and never actually starts recording, and usually I have to restart the computer. Is the burner junk? The drive reads discs fine. I called tech support, but they were useless, and to ship the drive would be a waste of money, cheaper to buy a new one. I was thinking of upgrading the firmware with the lite on firmware, would this make a difference?
