Is MythTV getting the TV signal from a firewire input or from S-vid?  If 
its s-vid, I dont think you can use the firewire connection to change 
the channels for that input.  As I understand it (which very possibly 
could be wrong) you can only change the channel thru firewire if the TV 
Signal comming to your MythTV box is thru firewire.  Reading the 
response from Ian, he says "In mythtv-setup, when you setup a *firewire 
input*, you should see the option for internal firewire channel changing 
in the same place that you normally see it for capture cards - in "Input 
Connections", leave the "External Channel Changing Program" field 
blank..." he says to set up a FireWire INPUT, not s-vid.
