That's fair enough, but if you only look at frequencies where nothing is 
being transmitted you're unlikely to see anything.  The other SD freq is 
690 MHz.

I find vlc useful for testing, and for more general use; don't know if 
you have that.

Here are the first lines for each of the four transports that I saw, as 
terminal output from mythtvsetup in mid-December.
