    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 *** 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
    next writeable LBA 0
    CUE ***:

    41 aa 01 14 00 4b 13 0f
    burncd: ioctl(CDRIOCSENDCUE): Input/output error

    and syslog have this:
