So I have my MythTV system basically up and working, except for two things. The biggest problem I'm dealing with now, is that MythTV won't change the tuner's channels correctly after boot.

In order to get it to work, I've had to log into a root console and type:
rmmod ivtv
modprobe ivtv tuner=50

After that, everything works fine. But this is a problem, because it means if the power goes off and comes back on, the system basically won't function until I can fix it.

Does anyone know what might be causing this problem, and how to fix it? For reference, I'm using a PVR-150 with Knoppmyth R5D4. Below is the boot-time output of IVTV, obtained using "dmesg | grep ivtv". The output when I rmmmod/modprobe looks exactly the same.

The only difference I can see is that when I rmmod/modprobe, I'm giving it the 'tuner=50' parameter explicitly. Is there any place where I can set that in the bootup scripts? I'd just like to avoid having to modprobe every time.

Anyway, hope this questions hasn't been asked before; I did some searching and haven't found a solution.

Bootup output:

That seemed to do it; thanks!

(I just added an options line to my modprobe.conf and rebooted.)
