Soemtimes if the switch back do not help, i switch to some other channel which 
works almost any time. Then i wait until the OSD is gone and try the desired 
channel again.
It sounds silly, but i have the "feeling" that my frontend  can "stabilize" 
itself on this channels again.

It's no official patch from the list. When someone published the patch which 
considers the frequence i played around with the values. And i get the best 
result with the patch below (i know that i could remove the if ;).
