Yes, I want to replace the software on the remote.

Remote codes are not all that difficult; there's a database of remote codes.

The thing that irritates me the most about the Harmony remote is that there's no way to program a macro, except for the "Activities" list. Once I've selected an "activity", one button produces one code, and that's it. I'd really like to be able to, for example, press a single button to turn on my closed captioning, but that would require a macro. So I can't do it.
