Hi Luigi

I currently use two of these cards in a linux box with mythtv, but would
love to get DVB support in FreeBSD so I can get rid of one more linux
box. I'm afraid I've never written/hacked on device drivers, but I can
certainly test/help out. 

(from further on in the thread) Finding the appropriate firmware file
for my card was quite difficult. The v4l-dvb drivers provide scripts
which fetch driver packages from manufacturers and extracts a firmware
from them, which can be a problem when the manufacturer stops
distributing the driver!

On my linux box, the Asus P7131 Hybrid uses these kmod:

and the dmesg (probably not that helpful!)
