BTW - do you have a cdrtools users list? Maybe this is too off topic
for many Gentoo users? If this bothers anyone please let me know and
I'll try to take appropriate action, assuming there is some place else
to have such a conversation.

Indeed, in the files created by the LITE-ON DVDRW LDW-411S (my drive
1) I see bad characters:

CDINDEX_DISCID= 'YasSG0mWGVxInJOH.LN2lnPcBoY-'
CDDB_DISCID=    0x870dbf0b
MCN=
ISRC=           0@-405-72-00001

While in the files created by the LITE-ON LTR-48246S (my drive 2) I
see no characters:

CDINDEX_DISCID= 'YasSG0mWGVxInJOH.LN2lnPcBoY-'
CDDB_DISCID=    0x870dbf0b
MCN=
ISRC=

OK, so we've made a little headway. Buggy firmware in drive 1. So I
did the cdda2wav step using drive 2 and wrote the new disc using drive
2 also. This disc plays in the car, but only the first track! From
track 2 on I just hear the head seeking around and (apparently) not
finding what it's looking for. But that's an improvement!

Here are the results from the copy/write of the disc on drive 2:

Now, I didn't use paranoia, and I didn't control the speed. I can try
a few experiments with that. I can also try reading on drive 2,
writing on drive 1, or writing on another system that doesn't use
LITE-ON drives. Since the first track wrote at the slowest speed I'll
try controlling speed to be below 26x.

Is it possible to update LITE-ON firmware?

Thanks,
Mark
