Please help: burncd errors

[Xinizul Xinizul]

Hello all:

I'm trying to burn an iso image containing a folder of mp3 files.

I'm using FreeBSD 5.3 and I'm using my Pioneer DVR-A06 DVD / CD Writer: 

-bash-2.05b$ dmesg | grep acd
acd0: DVDR <PIONEER DVD-RW DVR-106D/1.08> at ata0-master UDMA33


I'm using burncd as the handbook' chapter 16 explains but I obtain the
following error:

192# burncd -t -f /dev/acd0 audio mp3_1.iso fixate
next writeable LBA 568
writing from file mp3_1.iso size 771328 KB
written this track 955 KB (0%) total 955 KB
only wrote -1 of 37632 bytes: Device busy

I've tried with several speeds as suggested on the www  but the result
was the same.

It seems this is an old known error.

Can someone help me please ?

Thanks and Happy New Year,

Xinizul
