Brandon,

VIDEO_CX18 selects VIDEO_TUNER , but you chose the option, 
"MEDIA_TUNER_CUSTOMIZE" , which turns off the automatic tuner dependency 
selections.  Please note the description of this option:

menuconfig MEDIA_TUNER_CUSTOMIZE
        bool "Customize analog and hybrid tuner modules to build"
        depends on MEDIA_TUNER
        help
          This allows the user to deselect tuner drivers unnecessary
          for their hardware from the build. Use this option with care
          as deselecting tuner drivers which are in fact necessary will
          result in V4L/DVB devices which cannot be tuned due to lack of
          driver support

          If unsure say N.


We allow users to disable certain modules if they think they know 
better, and choose to compile out drivers that they don't need.  You 
should not have disabled tuner-simple -- to play it safe, don't enable 
MEDIA_TUNER_CUSTOMIZE

Regards,

Mike
