Hi,
I sum up my problem and his solution, maybe it'll help someone in the
future.
Few weeks ago i wanted to make run my Miro PC/TV (bt848, 2 crystals,
Philips Pal/Secam tuner) on my freebsd box.
so i tune my kernel:
device bktr0
options OVERRIDE_TUNER=6 # Philips Secam
# i2c
controller smbus0
device smb0 at smbus?
controller iicbus0
controller iicbb0
device ic0 at iicbus?
device iic0 at iicbus?
device iicsmb0 at iicbus?
Well all is detected at boot. So il configure fxtv with the good
frequencies.
I launch fxtv, surprise: only distorded images :((
So i try all configurations in the kernel, but no way...
After search, and contacts on french mailing-lists and newsgroup: i
release that i'm not alone with these pb!
Secam tuner seems not work with freebsd's bt848 drivers...
So i posted on freebsd-question and Juha Nurmela (thanks to him) give me
the solution:

I had the same pb with my second tv card : Guillemot Maxi TV Pci2
(bt878, one cristal, Philips Pal/Secam tuner) and it runs with the
source change. The card is detected as a FlyVideo by the kernel (i
use last driver). All is good but when i switch channels i hear bad
switching noise...
I try to change the CARD_FLYVIDEO record with the help of the bttv.c
but without good result...
Marc
