I'm going to be looking at simplifying tuning next week, this should
make things a little less wonky. Right now everything should work,
but since three threads must be coordinated it can take a while.

The UK "off-air" problem by all rights should be solved, there are
two points in the tuning that check for this... but then I'm not in
the UK so something obvious may be missing here.

This is probably just happening because you've turned debugging on,
you can comment out the code in SIParser::ProcessUnknownDescriptor(...)
if you don't want to see those, but still see other debug messages.

I didn't do this :) You might want to try changing OSD themes...
