Have you tried this in safe mode? I actually don't know if burning will work or not, but it will limit the number of variables.

Just tried it. In Safe Mode, I can burn & verify (Finder, DU, Burn), as expected. Works fine, until the free list is tiny - then either the burn or verify fails. No errors were thrown into the reg console or system logs. The only error is a simply verify failed message. Even tried a few at 2x, no change. eg:

Burn: Burn started, Sat Apr 14 13:24:40 2012
Burn: Erase started, Sat Apr 14 13:24:41 2012
Burn: Erasing in PIONEER DVD-RW  DVR-127D B912 via ATAPI.
Burn: Erase finished, Sat Apr 14 13:25:12 2012
Burn: Burning to DVD+RW media with DAO strategy in PIONEER DVD-RW DVR-127D B912 via ATAPI.
Burn: Requested burn speed was 4x, actual burn speed is 4x.
Burn: Burn finished, Sat Apr 14 13:38:13 2012
Burn: Verify started, Sat Apr 14 13:38:13 2012
Burn: Verify failed, Sat Apr 14 13:39:56 2012

Since I had the machine down, I ran another set of verify disk passes on all volumes - clean. Cleared caches, applejacked, etc. No diff.

Just a WAG but could it be a drive firmware problem?

hummm. I bought the burner from OWC several years ago and transplanted it to my QuickSilver late last year. You've reminded me that there is a firmware update for it -- to enable DL and 16x burning. Just applied it! Works nice. Thanks for reminding me about it!!!! But... made no change in the problem at hand.
