Hello! Some short time ago I have asked the same question. I am using latest drivers from Steven's repository at http://linuxtv.org/hg/~stoth/hvr4000 with patches from this mailing list. Frontend CX24116 is shutting down on exit from szap and szap2. Manu and other guys told me that I must to increase dvb_shutdown_timeout or set it to 0 to avoid frontend shutdown. Today I have tried to set dvb_shutdown_timeout to 0, 1000 and 1000000 at modprobe.conf, than hardcode it in dvb-core/dvb_frontend.c dvb_shutdown_timeout to 0, 1000, 100000 and 1000000 recompile the drivers for each value few times. Also I was using szap and szap2 to tune up the frontend. The situation was the same in any cases: if frontend was not in use by any running program it was shuts down on exit from szap or any program that was kept frontend in use (like dvbtraffic). When I have tried SS1 timeouts works fine! Is it mystique? -- Vasily Petrushin +7 (916) 605 90 12 _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
