6636	external channel changer not getting channel number passed in	dominique@…	Isaac Richards	"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):
