I had a fluke with a burn I made today where the Device Buffer was barely filling and the burn went very slow (would have taken four hours so I cancelled it). Checked the logs against the log made during a successful burn yesterday with the same discs. Turns out my external usb 2.0 drive was detected as usb 1.1 for some reason (suspect it happened when I had it in sleep). Disconnecting the drive and plugging it back in fixed the issue and I was able to burn normally though sadly I made a coaster out of a DVD-DL disc.
