trying to find causes for high cpu usage

I added some debug output for every 1000th call to poll()
in cSectionHandler::Action

At 23:58 a recording started. Since then the thread for
my 2nd device (first and primary is Nexus-S FF, 2nd is TT PCI Budget)
also polls much more even after the recording finished.

Why is there so much activity going on for the 2nd device even when
it is no longer needed?

Is there any way to tell vdr that no output is needed such that
vdr can stop processing the data stream of the first device too?

Why does the first device call poll() twice as much as the second one?
