  	  By default, a media driver auto-selects all possible ancillary

  	  frontends, that are used by any of the supported devices.
  
  	  This is generally the right thing to do, except when there
  	  are strict constraints with regards to the kernel size,
  	  like on embedded systems.
  
  	  Use this option with care, as deselecting ancillary drivers which
  	  are, in fact, necessary will result in the lack of the needed
  	  functionality for your device (it may not tune or may not have
  	  the needed demodulators).
  
  	  If unsure say Y.
