You are absolutly right, since there is to many transponder/transport streams 
on dvb-s, and there is no sense in sending the epg on all transponders..

About the implementation specifics, I would have put a thread in a class that 
has a close connection to DvbRecorder, and make it abortable (or maybe 
pausable) as soon as startRecording is invoked in DvbRecorder, and resumable 
after a certain period of idle time (10 min?). Use qt signals for the 
communication between the two classes, to keep the loose binding.
