We all are. I was asking on a more prosaic level.

Specifically, what devices are colliding or causing you trouble? From what I've read it sounds like two analog tuners are causing myth headaches so...

It should be pretty easy. Each device uses a different driver so you don't have to try very hard to put together a matching condition. Something like this would work for your hauppauge card:

    SUBSYSTEM=="video4linux", DRIVER=="ivtv", SYMLINK+="video-pvr150"

Reboot, verify that there is a /dev/video-pvr150, and then in myth-setup change the hauppauge tuner's device to be the symlink instead of /dev/video0 as it likely is. You should now be insulated from kernel device renumbering.

For your other analog tuner do one of those udev attributes dumps and make a new udev rule with that card's driver and a new symlink. Then create a new tuner in myth using that symlink.

I'm not clear if you have a problem with digital tuners but the drill is similar. The subsystem would be "dvb" and the driver name would come from further udev dumps. Use the symlink name in myth-setup.

Oh, udev rules typically go in /etc/udev/rules.d. See what's in there already and create a new file with similar naming.
