 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.
