Yes.  This is how I did it.

I included these and then restarted the backend.  No messages.

I'm not sure what you mean here. 

I've found a bit more.  Seems channel changing works when specifically 
entering a number such as "13_1".   When I do this I also get output in 
the backend log.  Thus it appears that the UP/DOWN arrow keys are not 
valid for channel changes however they do make the OSD show up like it's 
going to change the channel.

How can I restore the UP/DOWN key function when watching Live TV?

Thanks,

Drew
