I had this problem until I wrote some udev rules to make sure they  
always come up as the same device.
The only difference between them are the serial numbers so you need to  
use those in your rule. These are mine:

KERNEL=="video[0-9]", SYSFS{name}=="Hauppauge HD PVR",  
SYSFS{serial}=="00A20C53", NAME="video0", SYMLINK+="HDPVR0"
KERNEL=="video[0-9]", SYSFS{name}=="Hauppauge HD PVR",  
SYSFS{serial}=="00A200E1", NAME="video1", SYMLINK+="HDPVR1"
