Your in the DVD Shrink forum, and this is a Nero question. I will give a go at your log though. If this is the correct drive, your firmware is out of date; http://forum.rpc1.org/dl_firmware.php?download_id=1986 I couldn't find the exact model as yours doesn't have the S on the end of the model number. looks like you may be trying to put a PAL movie on to an NTSC system without converting it. AVI2DVD a free program will convert PAL to NTSC. http://www.afterdawn.com/software/video_software/video_tools/avi2dvd.cfm this may be firmware out of date. It also looks like you were using the Burn At Once option. I usually get coasters whenever i try that with Nero. Uncheck the disc at once and give that a try. I am a novice at looking thru Nero burn logs. Creaky is the expert on this. There are probably a few more things hidden in this log, but that is what i see standing out for now. I will see if i can get a Mod to move this to the Nero forum.
