  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.
  73
  74           Say Y when you have a TV or an IR device.

 133           This option enables DVB Network Support which is a part of the DVB
 134           standard. It is used, for example, by automatic firmware updates used
 135           on Set-Top-Boxes. It can also be used to access the Internet via the
 136           DVB card, if the network provider supports it.
 137
 138           You may want to disable the network support on embedded devices. If
 139           unsure say Y.
