Don't top post, always reply to the bottom of the thread or inline. No idea, possibly, this is likely a common problem on many different bridge drivers if/when the demux is closed and the demux is released. How do you plan to tune the app anyway? Why not have that app monitor the signal strength and thus keep the device open? It's not clear whether changing the default thread value (module param - exact name escapes me) for closing the frontend will help here also. (The module parameter defaults to automatically close the frontend after 3 seconds of idle time).... Try increasing it. - Steve _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
