Direct TV and Concertone

Does any body know what code I would use for my Direct TV remote to control the Concertrone RX75? It would be nice to use 1 remote. Any help would be great

I researched this on the web after my Concertone remote failed. I wanted to be able to control the Concertone with one of the high end remotes that you can by at Radio Shack or Best Buy.

According to a couple of the sites that I looked at, Concertone says they use proprietary codes that are not available to the public.

With all the problems that we experience with these sets, its a wonder that FR still uses them.

I wonder what the other guys use?

I tried do search`s on this a few years ago and came up empty.
I also went through about an hour of trying the manual scan on the remote with no luck.
I did however get a RF remote from directv so i can control the channels from the outside of our cat, but still need the concertone remote to control the volume.
If you have any luck please keep us posted.
