I maybe mistaken, but it looks like NevoStudio Pro does that. I just tell it what device I have and it connects online and downloades the codes. I only had to learn a couple of commands, all of the others it pulled down automatically. The only commands I had to enter directly were on/off for my Onkyo T-4555, which I found here and entered pretty easily into the studio. They're actually better than the Onkyo remote, which is only a toggle, whereas the commands I got here (thanks sydinstaller!) were discrete ON and OFF.
