Hi Pete,

Yes, the frequencies I'm using are:

  Mux 1 = 578000000
  Mux 2 = 850000000
  Mux A = 713833334
  Mux B = 721833334
  Mux C = 690000000
  Mux D = 538000000

I get the same results independent of QAM and FEC settings.  The strange thing 
is the way that I'm randomly given the channel information (i.e. the station 
names) for Mux 2 whether or not it's tuned to that frequency - the fact that 
this is one of the weak QAM64 muxes is odder.  Other times I just get the 
fd_sdt error.

In fact in testing yesterday, I occasionally got the Mux 2 station list when 
tuning to muxes 1, A, and D, and got the Mux B station list when tuning to Mux 
2!  At the same time, the PC next to this one was happily showing the correct 
stations using a Nebula under Windows.

I know the frequencies are correct as they're the ones I used before when the 
Nova-T was working OK under Linux, and I've verified them with my set-top box 
and my Nebula under Windows.
