I've been having problems burning dvds with Nero. I've tried everything even enableling the IMAPI in Window XP. Maybe it's not a nero issue? i don't know. At first it would create errors including Uknown Burn Phase and burn disks that won't play or can't explore on the computer. Here's the log of my last burn attempt. I hope this helps and you can help me.
