Well I unfortunately have a alot of experience with the M179's. I'm using
FC3 with one of the later
rc3 ivtv versions on a test box and it works fine. Granted I'm not using a
amd64 system but that
shouldn't have anything to do with it. What does your modprobe.conf look
like? I will say the
M179 is very very stubborn. You usually have to trick it especially on a
reboot as this card doesn't get
autorecognized by ivtv. If your getting static then thats a good sign. What
I have to do sometimes
is change the tuner to something that doesn't work then change it back to
the right one. Like so,
ivtvctl -p 0 ivtvctl -p 3. If composite(3) is what your using.
