This is sort of what I have done to get the external channel change 
command working again. The other piece is to temporarily disable the 
external command by adding set externalcommand = '' (that is two single 
quotes) to the update mysql command above. Tune to the channel and then 
re-enable the externalcommand by updating the entry with the appropriate 
external command. This is a one-off procedure after restarting ivtv (or 
a reboot, of course). After that the tuner and STB will work correctly 
until the next time the ivtv module is restarted.

Yeah, the problem is that the ivtv module gets loaded first, which, 
hauls in the tveeprom-ivtv module and the bttv module (maybe the 
submodules it needs?) has conflicts. Now, why his setup with only the 
PVRx50 needs to load the bttv module is a new one on me. My system has 
this problem but I'm using multiple PVRx50s and a FusionHDTV5 Lite. I 
have to manually load the bttv module first and then the ivtv module 
before it works, at least, partially.
