[mythtv-users] changechannel support for DirecTV tuner

[Felix]

Hi,

I am trying to conrol DirecTV tuner from MythTV (DirecTV Receiver D10). 
I read:

    If you have an external tuner, such as a DirecTV or digital cable
    set top box, you should add |/usr/local/bin/changechannel| to your
    Input Connections in the mythbackend configuration GUI. The
    *changechannel* program is not supplied with MythTV, so this is
    going to be dependent on what sort of external tuner you have.

Is there a changechannel for DirecTV tuner anywhere?

Thanks
Felix
