As usual Juri is right :-)

I have a very lousy signal here in Berlin. Most channels have a siganl level 
of 4xxx in tzap (im still searching for the reason for this low signal).

With the current CVS code i have to wait for several seconds until i have a 
stable picture and sound. With your patch this time is getting shorter for 
some channels.
But i also tried it with fixed values of 2 and 3 as third parameter for 
sp5659_set_tv_freq() (instead of the zero). And with a value of 3 i have a 
stable picture and sound nearly immediately on every channel.
The disadvantage seems to be that sometimes i get on switching only a black 
screen without sound. Then i have to switch to a complete different 
frequence, before a i can switch successful to the desired channel.

As you notice i do not know what i'm doing here. It is more trial and error :)

Greetings
  Nils
