EventGhost

Maybe something like this exists, but I am looking for a plugin to remap remote control events, like a plugin that says press up, down, left, right, dvd play, stop etc. and that will go through the currently loaded xml and replace all the remote triggers with the newly mapped ones.

To remap you can open the config file in a text editor and use it's find and replace logic.
Fortunately the codes don't change that often.

That is possible, but I was looking for a GUI Implementation that asks you to press your key and then goes through the script and finds the specific key-flag and switches it to the pressed key.
