sure, you can always set arbitrary filters on the transponders you tuned 
to. But when you tune to another frequency the transport stream to your 
transponder will disappear and another one (w/o the data you expect...) 
will feed the demux. So any application which expects data out of the 
frontend is responsible to keep the frontend file descriptor openend as 
long it is relying on the transport stream from this particular 
transponder.

Otherwise the power management is allowed to shut down the LNB power and 
other applications are allowed to tune to any other frequency.
