burncd and DVD failure

Hi,
while doing (using -current):
   burncd -f /dev/acd0 -s max dvdrw /some/file.iso
(A 1.4GB DVD-RW mini is inserted)

I get on tty:
   ...
   only wrote -1 of 32768 bytes: Input/output error

And via syslog:
   ...
   acd0: TIMEOUT - WRITE_BIG retrying (1 retry left)
   acd0: TIMEOUT - WRITE_BIG retrying (0 retries left)
   acd0: FAILURE - WRITE_BIG timed out

Any clues?

This is an:
   acd0: DVDR <PLEXTOR DVDR PX-708A/1.08> at ata1-master UDMA33
hanging on an ASUS A8V-Deluxe AMD64 machine with 2GB Mem.

I used atapicam successfully in the past BTW.

Additional infos needed?

Bye/2
