Is there a good primer somewhere on how to set up modprobe with multiple 
cards?  I have a BTTV and a PVR250, the bttv is detecting first, and changes 
channels fine, and the PVR250, I can't change channels at all.  I've tried all 
the usual stuff, like permissions on /dev/video*, etc.  But I'm not entirely 
sure that the tuner is configured correctly.
