When you stop *zap, the default behavior of dvb-core is to switch off
the frontend after a predefined period of time, to save power. So what
you are seeing is the default behavior. If you want to turn OFF this
behavior, you can use the module parameter dvb_shutdown_timeout=0 to
dvb_core, such that this feature is disabled.
