Not that it speeds up the process of reassigning cards/inputs, but I 
have a suggestion. Assign each input a unique name that lists everything 
about it. For instance, I have something like this for my two Dish 
Network receivers:

   Dish 1 (bottom, PVR250, /dev/video0)

   Dish 2 (top, PVR350, /dev/video1)

This helps greatly when trying to debug things later on. ("I'm not 
getting any audio. So, which cable is it? Do I get audio if I pipe the 
dev through mplayer?")
