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.
