Re: Problems with Matshita UJ-810
Hi,
I'm returning to this issue, because I've run into it harder than ever
before:

It seems I get best results with Verbatim-DVDs (no failures since
then), unfortunatedly every other vendor I've tried (add memorex,
imation to the list), doesn't succeed the OPC part.
I'm still using 5.11, and looked at the download pages. So 5.5. is an
older version? Does it have a switch to turn OPC off or is this simply
not yet implemented in 5.5.x?
I guess it would be good to have a switch for that as seen in Nero
Express..
I didn't find a Changelog page at
http://fy.chalmers.se/~appro/linux/DVD+RW/, so don't know whether the
current 5.17.x has some improvements in this area.
It seems, I run the latest firmware, and don't suffer from any kernel
bugs. Probably the drive is not very DVD-R conformant. It seems it is
primarily a DVD-RAM device and as such works flawlessly.
