I tried 2. Didn't want to waste any more in case it actually did write

According to growisofs (i think it was) the drive has ~1100Kb
buffers. The rest must be used internally for other things.

I fear that might indeed be the case. Or the laser for the DVD+R/DL
burning is dirty.

I will have to see if I can borrow a newer drive from my sister over
x-mas (depends on if she brings it). From looking at the scsi log and
what you said I don't believe this is a software fault so feel free to
close the bug.
