Remember that comment about the strangest situations? This client LOVES his MX500 that's a dozen years old and in perfect clean condition. He modernized his TV and AVR and wants to use the same remote. Try finding the files for THAT!

I'll be putting codes into another URC model, then teaching them to the MX500. It's what the client wants and will pay for, despite the lack of backup that all more modern remotes give us.
