Thank you for the help.
The line in modprobe.conf is :
alias char-major-81 bttv
options bttv card=39 tuner=33
but the system doesn't seem to take care of the tuner type it seems to
autodetect it. But i don't know what type of tuner i have. The line was
added by system the first time it detects the card. If i put tuner=3 i
find tuner=33 in dmesg.
I think to a kernel module problem in this kernel version because with a
previous (do not remember which release) it worked fine!
There is also this error in dmesg when i try to change channel in
tvtime:
tuner: tv freq set to 767.25
mt2050_set_if_freq freq=767250000
lo1 lo2 = 496 294
num1 num2 div1a div1b div2a div2b= 1 b66 28 4 23 6
bufs is: 1 11 28 cb 66 63
mt2050_set_if_freq failed with -121
mt2050: enabled antenna connector 1
Maybe i will send a message on devel list ??
No one else has problem with bttv ?
Best regards
