The only issue I have yet to figure out with this method is when using specific lines on my RF base station.

I have told the MX-810 that my XBox changes the channel and to set all other buttons to the XBox device. I currently have my XBox signal to only output through line 3 on my RF base station.

When I use this type of activity, all the hard button's signal for the XBox activity are passed to line 3, which is the XBox assigned line and is correct.

HOWEVER, when I manually assign a command to the ON Screen custom icons of the XBox activity, by dragging a command in the browser, THOSE commands are inexplicably outputting its signal through line 4, which is for my Directv receiver. I cannot seem to make the onscreen custom button commands output their IR signal through the proper line 3 to match the hard buttons.

I'm currently forcing the XBox to output its ir signal to all lines to get around this but I'd sure like to know how to force the on screen icons to output to the proper line.
