[mythtv] FTA Satellite developer wish list

Fundamentally the issue we have is that none of the developers have
any of the hardware required to work on this or be in a position to
test it.

We can help by reviewing code, working with you to understand what
is happening (especially with your wide band LNB), and help to
improve MythTV in this area.
