  74           needed in order to support several video capture adapters,
  75           standalone IR receivers/transmitters, and RF receivers.
  76
  77           Enable this option if you have a video capture board even
  78           if you don't need IR, as otherwise, you may not be able to

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

 188           By default, a media driver auto-selects all possible ancillary
 189           devices such as tuners, sensors, video encoders/decoders and
 190           frontends, that are used by any of the supported devices.
 191
 192           This is generally the right thing to do, except when there
 193           are strict constraints with regards to the kernel size,
 194           like on embedded systems.
 195
 196           Use this option with care, as deselecting ancillary drivers which
 197           are, in fact, necessary will result in the lack of the needed
 198           functionality for your device (it may not tune or may not have
 199           the needed demodulators).
