My apologies, I've been away from Pierogi for a couple of weeks; I'll have to make some time and get back to updating the app. I've done a quick check, and found at least one Mitsubishi projector keyset in the LIRC collection. (It's using the "Proton" protocol, and yeah, I don't currently have a matching keyset in Pierogi yet.) I'll try and get it into an update soon...
