Thanks for your efforts. I updated dvb-kernel from CVS and tried that 
timeout fix but unfortunately it didn't fix the problem... Sure it's better 
than the CVS version with shorter timeouts but it still doesn't work better 
than my previous experiments with increased timeouts. I'll try to play more 
with the values in stv0297.c but maybe the problem is something else.

I've tried to increase every "timeout section" ("wait for...") in the source 
code step by step to be able to successfully move to the next section but 
sometimes even waiting 1-2 minutes isn't enough...

Is there any documents in the net that I could read to be able to understand 
better how the tuning process and these drivers works? Studying the source 
code doesn't help me much since I lack the basic knowledge of this whole DVB 
system.

BTW, how can I change PWM values in the current driver? I managed to find 
this:

But I can't find any pwm values anymore (moved to some other place?).
