No, you've hit the nail on the head. I just don't know how to get Myth to  
send
anything other than the channel numbers. Actually the DCT2000 serial  
application
includes all the remote buttons (if you look at the remote.h file in the  
source
folder you can see all the button lables supported) but since Myth handles  
the
channel change internally I don't know how to get it to send the other  
commands.
I had thought I had a work around by using dummy channels and adding a case
construct to the DCT app to intercept the dummy channels and change them to
the codes that I wanted and it worked beautifully until I wanted 2  
consecutive
downs. Myth doesn't send the channel to the tuner if it is already on the
requested channel.

If there is a way to send commands other than channel numbers through the
external tuner mechanism that would be fantastic but I don't see it. I  
would
love for someone to tell me I'm blind and that it's already there, just do  
this.
