Oh Boy, now I am ready to throw my towel. It all stopped working again, back to square one. It worked for 3 burns, 1 cd 1dvd 1dl and then puff coaster cd's 0.3x dvd's and coaster dl. For some reason simulate write does not work, tells me drive does not support it. I think i will just put this sony back in for now...<br>

</div>Oops. Buffer underrun with DVD+R DL ?<br>
That should not be possible.<br>
DVD+R may have open more than one track and<br>
thus have to stand that writing to a particular<br>
track gets suspended for a while.<br>
<br>
Also, they do not get sent a mode page 5,<br>
which could have the BUFE bit set for<br>
burn-proof.<br>
Up to now i thought that one cannot disable<br>
burn-proof with DVD+R [DL].<br>
<br>
Well, DVD+R DL have caused lots of problems<br>
on my drives. Mostly with readability, though.<br>
Coasters were rare. (But my Samsung SH-S203B<br>
went blind for DVD+R by too many tries with DL,<br>
i supersticiously believe.)<br>
<br>
Blu-ray is the future. It works already quite<br>
well. Only prices are still too high.<br>
<br>
<br>
The best benchmark for speed are DVD-R because<br>
one can burn them in simulation mode. That way<br>
the media stays blank and can be used for the<br>
next try.<br>
cdrskin ... -dummy ...<br>
growisofs ... -use-the-force-luke=dummy ...<br>
<br>
I never tried whether wodim or cdrecord do -dummy<br>
on DVD-R. Chances are that they do.<br>
