This is the contect of my custom rules to allow me to fix the device 
names of my PVR250 and a BT878 device (which I don't use in myth):

KERNEL=="video[0-9]", SYSFS{name}=="BT878*", SYMLINK+="BT878"
KERNEL=="video[0-9]", SYSFS{name}=="ivtv*", SYMLINK+="PVR250"

then in mythtv-setup I specify /dev/PVR250 in the devoce name instead of 
/dev/video0

Regards,
Dave.
