I spent a few minutes googling this and had no luck. Wanted to throw this out there for some opinions:
Short version:
Burner: Brand New Pioneer DVR-S18MBK with latest Firmware.
Media: Verbatim DVD+R DL (MKM-003-00) (Unfortunately not the 2X)
I've been able to successfully burn 2 of my backups so far. It always has this error when starting, but continues anyway.

I am having an issue with a different backup thought - see the very bottom of this log:

I got this same error twice. What's interesting is that it still plays in my 360.
Any thoughts? Is this a non-issue?
