  66           Enable support for Remote Controllers on Linux. This is
  67           needed in order to support several video capture adapters,
  68           standalone IR receivers/transmitters, and RF receivers.
  69
  70           Enable this option if you have a video capture board even
  71           if you don't need IR, as otherwise, you may not be able to
  72           compile the driver for your adapter.

 130           standard. It is used, for example, by automatic firmware updates used
 131           on Set-Top-Boxes. It can also be used to access the Internet via the
 132           DVB card, if the network provider supports it.

 177           By default, a media driver auto-selects all possible ancillary
 178           devices such as tuners, sensors, video encoders/decoders and
 179           frontends, that are used by any of the supported devices.
 180
 181           This is generally the right thing to do, except when there
 182           are strict constraints with regards to the kernel size,
 183           like on embedded systems.
 184
 185           Use this option with care, as deselecting ancillary drivers which
 186           are, in fact, necessary will result in the lack of the needed
 187           functionality for your device (it may not tune or may not have
 188           the needed demodulators).
