[mythtv] Freesat EIT

[Roger James]

Hi Stuart,

As far as I can see I have not changed the logic of the Freesat handling. 
Is it working in the current master? It is difficult for me to tell. I have 
been jumping down a rabbit hole assuming I had broken something in the code.

I am getting too old for this.

Roger
