I tested the code from CVS which includes controller stop and start and the 
sp8870_readreg calls in the FE_RESET case over the night again.

My impression is that is does not really change something at tuning or 
lockups. As the problematic channel is again the old one, i guess that the 
"troublesome" channel is related to the temperature or power.
I would say that no the sound comes before the picture, if this interesting. 
One good thing about this new code is that the CPU load is very low if i 
switch to a channel where i do not get picture after 2 seconds. I remeber 
that tuning on such "troubelsome" channel caused definite load for some time 
during "channel search".
The second good thing is that i now sometimes get a picture after several (10 
or maybe more) seconds, where before i could switch back if i didnt got a 
picture after 5 seconds.
In general i would call it an improvement.

Sorry if my descriptions sounds so relative or undefined.

Thanks for all the support
  Nils
