The m179 is the same setup in the fedora mythtv howto by jarod. It's pretty
straight forward and the quality is just as good or almost as the pvr250.

Alas, Avermedia will only take their card back after 14 days. To save others
some hassle, I don' recommend using the m179. When I had it running under
windows, the picture quality wasn't real good, and I think the PVR150 from
hauppauge must be easier to get working, and it's about the same price.
That said, I will try to get this sucky card working since I'm stuck with
So here's my latest thought (I can only muster up one at a time). Does the
m179 use the same firmware as the hauppaugge? To anyone who has a working
m179, what firmware are you using?

I've tried your trick Dennis, changing the input with ivtvctl, to 3 and
backto 0 (I'm using the coax input), but it still doesn't work. Now, going
back to the latest gentoo driver, I don't even get a picture, just static,
or blank screens when I have a different input.
I've attached my modprobe.conf file. As things look now, though, I'll return
the m179 and get a PVR150. I think that should be easy to get working, and
there isn't much price difference.
