Sounds to me as though you don't have the channel number set up correctly
in mythsetup. Note that for each channel, the channel number is on the
second page of the setup (I think its the 1st field of the 2nd page) - if
this is blank then you'll never change channel, either internally or
externally (as both methods use the same field for the channel number
info).
