I keep getting this error (the one in the attachment) when I try to burn a DVD in Toast 7.0.2. Also, my DVD burner is very noisy when it tries to burn the lead-out. I'm on a Rev. B iMac G5 (the last one before iSight) 20" 2.0 GHz, running 10.4.4. Does anyone know what this error means? I've burned CDs before, and I've burned a few data DVDs using Finder and Disk Utility.
