I have a DVR-A03 which I have used successfully to burn CDs with (this
version of) cdrecord (1.11a11). 

When used with DVD media (the sample piece which came with the drive) I
have had but one dummy burn succeed, and all others fail at a random point
with e.g.:
Track 01: 477 of 4443 MB written (fifo  95%).cdrecord: Input/output error.
write_g1: scsi sendcmd: no error
CDB:  2A 00 00 03 BB 4F 00 00 1F 00
status: 0x2 (CHECK CONDITION)
Sense Bytes: 70 00 04 00 00 00 00 0E 00 00 00 00 08 01 00 00
Sense Key: 0x4 Hardware Error, Segment 0
Sense Code: 0x08 Qual 0x01 (logical unit communication time-out) Fru 0x0
Sense flags: Blk 0 (not valid) 
cmd finished after 2.009s timeout 200s

write track data: error after 500856832 bytes
Sense Bytes: 70 00 00 00 00 00 00 0E 00 00 00 00 00 00 00 00 00 00
Writing  time:  221.003s

The CDB is different each time but always "2A 00 00 " something, the rest
is almost always the same (the cmd finished line seems to be varying by
.001s each time) 

The command is the same each time: 
cdrecord dev=0,0,0 speed=1 -v -dummy -dao /mnt/disc1

but I notice:
Starting to write CD/DVD at speed 2 in dummy mode for single session.

Will I have better luck if I make some change to actually run at speed 1?
Is there a guide on how to decode this information somewhere? Thus far my
searches have turned up fruitless.
