Trouble burning DVD
I am having zero luck burning DVDs (stupid system backups!) on my AMD 64 system

That's a bit confusing output; I have 3 relevant drives:
- ATAPI LG CD-RW, which appears to be the one on scsi bus 2
- ATAPI Pioneer DVD+RW, which seems to be the one on scsi bus 4
- ATAPI LG DVD+RW, hooked up externally, via FireWire, apparently on bus 5.
Either #4 or #5 otta work...
Another referencing is thus... sr0 seems to be the external LG DVD
drive; hdd looks like the internal Pioneer DVD, hdc is the LG CD-RW

I try writing a backup to the Pioneer drive:

I get the same message whichever I use, ATAPI:2,0,0, ATAPI:4,0,0, or
ATAPI:5:0,0.
The "proprietary" version of cdrecord is obviously no option as it is
available binary only, and AM64 is not one of the platforms for which
binaries exist.
What we usually use at work to burn DVDs is "dvdrecord," which is
apparently somewhat deprecated. I downloaded the sources for that; it
reports exactly the same problem.
A search for the message: "ERROR: unknow subsystem (scd0) in
(/dev/sr0)" shows that people have run into this; I have not yet seen
any actual answers.
I have modules sr_mod, cdrom, ide_cd, and sg loaded; that ought to
cover the kernel side, I'd think...
