Could you configure a tvh instance with only one channel and provide 'linuxdvb', 'epggrab' and 'eit' trace with a detailed description what does not work ?

oops, i didnt make myself clear. the epg comes from multicast input, not dvb.
here is a trace of eit from latest git with 1 mux/service/channel: http://pastebin.com/N0GcEuMk

and the problem was that the streams stay open w/o subscription thus adding traffic to my lo interface(no prob with 1 stream, but with 200+...) on my installed tvh i got 5 streams staying connected all the time and thats ~20Mbits/sec allready (see pic), or i just got it all wrong bit logfile says:

so i guessed the epggrabbber keeps em open...

anyway, keep up the good work !!

OK, I see. The EIT parsing looks good. Could you provide also 'epggrab,subscription,service' traces ? (using one channel <- one service config)..

same config,same service:

So OTA epggrab requests to unsubscribe the mux when the timeout is reached.. Could you also add 'mpegts' to the trace list ? It looks like an IPTV client code issue..
