  37                support both analog and digital TV. Disabling this option
  38                will disable support for them.

  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.
