[Dvdrtools-users] Sony DRU-500A and Pioneer DVD-116 reader: correction

[Jay Berkenbilt]

This is somewhat off topic, but I don't like to leave incorrect
information out there so.....

I wanted to post a correction to some remarks I had made earlier about
my experiences with the reading DVD-R discs written on the Sony
DRU-500A with my Pioneer DVD-116 DVD-ROM drive.  I had at one point
stated that I had some read errors on these discs that I had
attributed to writing discs at higher than their rated speed.  In
fact, it was all in my head.  It seems that reading from /dev/cdrom
(as in dd if=/dev/cdrom) always returns 0 (EOF) immediately with the
Pioneer DVD-116 and a DVD-R (but not a DVD+R) disc.  However, this is
a driver or software problem as it goes away if I use the ide-scsi
driver instead of the default CD driver.

Also, I've done some experimentation with writing DVD-R discs using
the latest dvd+rw-tools and am pleased to report so far that I have
had no compatibility problems.  I have also verified that the DVD-R
reading problems I have with my Pioneer reader (which has fewer
problems with the latest firmware but still has some problems) happen
with DVD-R seemingly regardless of where it is written.
