Then match some of those to my ~mythtv/.mythtv/lircrc. I've done that for a few keys but there has to be a better way. And, this still leaves keypresses sent to everything that might be listening because they simulate keyboard keys. What a schmoz!

I think you have a similar problem to me, although mine was slightly complicated 
by the use of the iguanaIR dongle.

Fortunately, I once used some PVR-250's to capture video and so had a genuine 
Hauppauge remote sitting on the shelf. I changed the lircd.conf to a Hauppauge 
one, restarted lirc and bingo! All the keys come out exactly as they are 
specified in the hauppauge .conf file.

This proved to me that my dongle -> lirc hardware-software chain worked as 
designed. It also proved that the alleged "Vista MCE remote" and dongle I had 
were nothing of the sort.

Testing the "MCE" remote, using the now-proven iguanaIR dongle and the "mceusb" 
.conf file, produced NOTHING, which I'm guessing is what you get. Using 
irrecord, the program verifies that this is, indeed, an RC6 remote but the codes 
are definitely NOT related to those in the mceusb .conf file.

If you can, try and find a known remote and dongle to test your system with. 
Perhaps the one that comes with your TV. Use irrecord to find out what codes it 
uses. Doing this may help eliminate particular parts of the chain so that you 
can concentrate on the rest.
