[linux-dvb] Question about consecutive tunings

[sabbi <sabbi@CS.UniBO.IT>]

Hi,

what's the safest method to make consecutive tunings? 

I usually use this method: 
	- if the transponder is the same I only change the PES_FILTER on
the new audio and video pid

	- otherwise I first tune, then change the filters on the
demuxers

but sometimes it locks. 
In the API PDF I dind't find anything relating to this situation.

Is it necessary to stop the demuxers before calling the tuning request?
Do I need to follow a specific procedure to re-tune?

Thanks,

		Nico
