What input are you using (i.e., Tuner, S-Video or Composite)?  Your 
symptoms sound like they have nothing to do with the external channel 
change script, but maybe you have your video source bound to the wrong 
input.  Either that or your using an external tuner connected to the 
Tuner input on you card (generally not a good idea).
