The bktr(4) driver & the LMLBT4x

[Achilleas Mantzios]

Hi,
i was trying to use the Linux Media Labs' LMLBT4M
with a 6.2-RELEASE FreeBSD machine. This card has 4 channels, no tuner, no 
audio. It is used primarily as a part of a security CCTV, (i am going for 
zoneminder.)

fxtv is giving me
ioctl(BT848_SAUDIO, 128) failed: Cannot allocate memory mmap of driver buffer 
failed: Invalid argument

Is there anything i can do with it?
Could it be a rather easy task to do? Or does it require prior FreeBSD kernel 
hacking experience?
i'd really like to do the job with FreeBSD instead of being forced to turn to 
Linux, which i left some 10 years ago.
Please include me in your replies, since i am not subscribed to 
freebsd-multimedia.
