 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.

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