Could you attach the gdb to the vdr process and check where does it hang

So, it's somehow related to cPatFilter. As the pid updating works nicely 
on my setup, this might be related to video stream data itself...

Did I understood you correctly: if you're setting the channel frequency 
to 10 instead of 1, your VDR won't hang anymore with section filtering 
(including PAT) enabled?

Why would "(abs(1-1)<4)" be different than "abs(10-10)<4"? Anyway, 
you could trace the values given to ISTRANSPONDER() macro and see if 
that gives any hint about the problem.

PS. You can also send bug reports and questions directly to me without 
polluting the mailing list.
