 78           if you don't need IR, as otherwise, you may not be able to

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

195           By default, a media driver auto-selects all possible ancillary
196           devices such as tuners, sensors, video encoders/decoders and
197           frontends, that are used by any of the supported devices.
198 
199           This is generally the right thing to do, except when there
200           are strict constraints with regards to the kernel size,
201           like on embedded systems.
202 
203           Use this option with care, as deselecting ancillary drivers which
204           are, in fact, necessary will result in the lack of the needed
205           functionality for your device (it may not tune or may not have
206           the needed demodulators).
