From all of my IR info and The info from HTM's site, There is only one IR code set for the DCT6200 and 6208 , which is the only one I seem to run across. As geraldB said, there was no change of codes listed in the manual and the remote instructions. I am sure it can be done if you have access to the operating system of the Cable box. I do not know of anyone with that kind of access.
