There may well be some transatlantic confusion here.  I have 1 PCI card 
with one physical tuner, and 1 USB dongle that includes two physical 
tuners. At a given time a physical tuner can receive signals on a single 
frequency/transport/multiplex/mux.  I have all mine set to be able to 
receive 5 'channels' in each 'multiplex';  the mythtv default is two. 
So I have 15 virtual tuners and could in principle record 15 programmes 
at the same time.  'Upcoming recordings' shows the virtual tuner that 
will be used for each programme.  That's all 'myth-legal'.

As before, HTH,
