burncd cd or dvd problem 5.2-RC1

Hi all,

I encountered problem in freebsd-5.2RC1 with cd or dvd burning with
burncd, cdrecord or dvd+rw-tool tools.
I have a sony-DRU-500a (dvdrw ide) and atapicam in my kernel (scsi ide
emulation)

For example, when i try a 'dvd+rw-format /dev/cd0' i get :
# dvd+rw-format /dev/cd0
* DVD±RW format utility by <appro_at_fy.chalmers.se>, version 4.7.
* 4.7GB DVD+RW media detected.
* formatting |- [unable to TEST UNIT READY]: Input/output error

does anyone have already solve it, perhaps in 5.2-RC2 ?

thanks in avdance...
