Biting the bullet and recreating my capture cards from scratch in cas
ethat had something to do with my previously reported sporadic problems, I
ran into this very same problem.
I thought it was me!
But, I too found that if I manually entered the frequencies used for ATSC
using the transport editor and then doing a rescan of just previously
defined transports, the mux data was decoded reliably. Incidentally, if
you do a dmesg out in a shell, you'll see a bunch of invalid modulation
method error messages being logged by the system.
Anyway, I grabbed the dvb-atsc-tools-1.0.6 source code from the downloads
section of the pcHDTV support site and found that its "dtvscan" program
worked flawlessly. Although the channels.conf file format can't be parsed
correctly by myth, the second field in that file it creates is the
frequency value in Hertz that you can then enter into the myth transport
Convoluted and complicated, yes, but it seems to work.
