[mythtv-users] Cards changing names

[Per Jørgensen]

Hey guys.

I'm having a problems that makes no sence for me.
I have 2 cards in my Backend

A Happage HVR-4000
and Hauppauge PVR-500

In mythtv-setup they change their names sometimes.
Sometimes it's the hvr-4000 that's are /dev/v4h/video0
othertimes it's the PVR-500 thats /dev/v4l/video0

I have both tuners in for the PVR-500 and the secund unit there are 
allways /dev/v4h/video2

Is there a way to make the cards static in their names - caurse the 
mythtv fails afterwards.
When HVR-4000 are video0
and PVR-500 are unit video1 and video2 then everything works?

So is there something I could do ???
Thanks
Pbj
