Could it be related to suspend mode ?

I "upgraded" my master-backend with a PVR-500 and a PVR-150 in it recently 
by restoring the DB and the recorded stuff to newer hardware (with newer 
Ubuntu from 7.10 to 8.10).

As I can now suspend the system to RAM instead of shutting it down (the old 
sytem could not be suspended), sometimes when it wakes up, the tuners don't 

As a workaround, I do these 4 steps when resuming:

1) stop mythtv-backend
2) rmmod -f ivtv
3) modprobe ivtv
4) start mythtv-backend

Since then, I never had problems with tuning errors.

I haven't yet found out how to automate this, but I am still trying, if 
someone has a good advice (Ubuntu 8.10).
