See if there is some updated firmware and my trick of recording at 1/2 (or lower) the rated drive or media speed.
I have been struggling for a couple months now to get my computer to burn a DVD-R disk. The computer works fine with +R but when I try to create a -R the disk writes a little information on the disk and then the drive and computer lockup. I have tried just about everything I can think of without lick.
Drive Type - I currently have an I/O magic drive but even purchased an Pioneer. With the I/O Magic I could write +R but not -R. With the Pioneer I could not get either to work.
Windows - I was using Windows2000 but just spent the weekend upgrading to Windows XP and it has the same result.
Software - I have used many software packages including Nero, ROXIO, and Pinnacle.
Disk Types - I have tried both Teon and verbatim Disks.
I have read other forums and found others having similar situations but no smoking gun.
