 I am having trouble using an external channel changer script from within
 mythtv.

 The channel changer works perfectly fine when run manually from the
 command line but fails when run by mythtv.  The error that I get is that
 the channel number, which is suppose to passed to the script as $1 is not
 being passed to the script.

 running mythtv backend in a verbose mode using the following command:

 mythbackend --verbose channel

 And this is the output I receive (also attached):
