Description
http://linuxtv.org/downloads/v4l-dvb-apis/FE_GET_SET_PROPERTY.html#DTV-LNA
Since a lot of users have problems with drivers that default to disabling the LNA built into their tuners we should implement support for enabling the LNA when using the card with MythTV.
My experience of handling user support requests in IRC and mailing lists suggests that most users need the LNA enabled, so the simplest solution would just enable by default with a GUI option to disable it.
A better implementation would automatically the LNA if the signal strength/quality falls below a reasonable threshold. The difficulty here is that signal strength can change over time and with changes in weather, so the very best implementation would be tied to the signal monitor and work per-tune rather than be set once when scanning.
