[mythtv] Testers wanted for DVB EIT rework

[Roger James]

Hi Piotr,

It is case one at the moment. When fully implemented it will significantly 
reduce the number of unnecessary passes through the EIT code. I also intend 
it to be the basis for the implementation of "accurate scheduling" using 
the EIT running status information.
