[mythtv] [PATCH]DVB setup truncation of dtv_multiplex table

	I agree dtv_multiplex should be truncated
(because otherwise a new set of identical
  entries would be created next time you scan,
  except that the mplexid would be higher),
but the old tables ( dvb_{channel,pids} ) shouldn't.
Suggest this, instead:

% cvs diff -u main.cpp
