That might be a better theory, indeed.

I kill on my machine the processes
  hald-addon-storage
which appear in ps -ef with the addresses of my
burner drives.


I once had a case where hald on an USB drive
caused cdrecord to report for a CD-RW in SAO
mode:
------------------------------------------------
Sending CUE sheet...
cdrecord: WARNING: Drive returns wrong startsec (0) using -150
Writing pregap for track 1 at -150
cdrecord: Input/output error. write_g1: scsi sendcmd: no error
CDB:  2A 00 FF FF FF 6A 00 00 1F 00
status: 0x2 (CHECK CONDITION)
Sense Bytes: 70 00 05 00 00 00 00 0A 2A 00 00 90 30 05 00 00
Sense Key: 0x5 Illegal Request, Segment 0
Sense Code: 0x30 Qual 0x05 (cannot write medium - incompatible format) Fru 0x0
------------------------------------------------

This looks very similar to the reported messages
with DVD-R.
A CD-RW TAO session failed with:

------------------------------------------------
Track 01:    2 of    7 MB written (fifo 100%) [buf  96%]  40.0x.cdrecord: Input/output error. write_g1: scsi sendcmd: no error
CDB:  2A 00 00 00 04 D8 00 00 1F 00

Sense Key: 0x5 Illegal Request, Segment 0
Sense Code: 0x21 Qual 0x02 (invalid address for write) Fru 0x0
------------------------------------------------

The problem did not appear with cdrskin.
Probably because libburn opens the device file
with option O_EXCL.
This is no insurance against hald problems, of
course. hald and burning of sequential media
do not play well together.


Have a nice day :)
