Compliance with the DVB power management specification (doesn't close
the tuner after having tuned). This permits to remove the parameter dvb_shutdown_timeout=0 to the module dvb-core and ultimately shuts down the card when the tuner isn't used. patch by Nico <nsabbi@tiscali.it> git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@11873 b3059339-0415-0410-9bf9-f77b7e298cf2
