ok i disabled hw.ata.atapi_dma="1" in loader.conf and this sovled the 
problem.
how ever, i still can't burn a dvd with growisofs. i run

titan# dvd+rw-format -blank=full /dev/cd0a
* DVD�RW format utility by <appro@fy.chalmers.se>, version 4.9.
* 4.7GB DVD-RW media in Sequential mode detected.
* blanking /

that finishes without error

titan# growisofs -use-the-force-luke=dao -Z /dev/cd0a=PubWare.exe
Executing 'builtin_dd if=PubWare.exe of=/dev/pass1 obs=32k seek=0'

:-[ WRITE@LBA=0h failed with SK=3h/ASC=73h/ACQ=04h]: Input/output error
:-( attempt to re-run with -dvd-compat -dvd-compat to engage DAO or 
apply full blanking procedure
:-( write failed: Input/output error

could it be the blanking procedure is the problem? theres a lot of doc's 
saying upgrade to 5.20 for dvd+rw-tools
my question, is why ship such an old crap version. i mean 4.10 isn't 
THAT old, these docs are bloody old old.
