I think I may have hit on something. I did sudo hdparm -d1 /dev/dvd once I 
logged into an XFCE session, *AND* (the important one) I replaced the stock 
40-wire IDE cable with an 80-wire one. I'm not getting a blank band on the 
first couple of burns. A couple more and this may be the fix.

My BIOS had been complaining that I wasn't using an 80-wire cable for the 
burner. It's not complaining anymore. :)
