This is unrelated to your original question, it simply means 
that these application do not follow the Microsoft 
specification on how to write multi-channel audio in wav.
(This is the same problem as "Remuxing multi-channel ac3 in 
avi doesn't work" which is reported quite often.)

You could try your original task with stereo (or mono) 
input just to make sure that the problem isn't that the 
FFmpeg dts encoder works badly with multi-channel input.
