Burning in DAO mode broken

Hi people,

I borrowed a DVD writer for this weekend and I'm a bit dissapointed
because I found that I'm not able to write anything in DAO mode.
Writing fails in sending CUE sheet with burncd, and just before writing
first data with cdrecord. I have -CURRENT from Friday night (17th Oct
2003). Blanking works fine, TAO writing works fine. Can anyone write CD
in DAO mode on -CURRENT?


# burncd -vnd data data.bin
adding type 0x08 file data.bin size 677280 KB 338640 blocks

and syslog have this:

<nothing got written on a CD>
