[mythtvnz] DVB cards changing

[Jason Taylor]

no problem... the bug says  /dev/v4l /* dont work.. I'm assuming thats
still true?

I've only ever done this with analogue cards but this is what I did

sudo python udev-rules-jaunty.py   /dev/video0   /dev/video_PVR150a
sudo python udev-rules-jaunty.py   /dev/video1   /dev/video_PVR150b

And that will walk you through the rest

Then in myth setup change the devices to /dev/video_PVR150a and
/dev/video_PVR150b

The /dev/video_ links will then always point to the correct device,
the /dev/video0 etc will still change
