Hi All, I have had my MX-950 remote for about eight years now and it works just great. I would like to find the ir codes for the vizio m-series M4221-B1, I don't have live update for my mx-950 text editor software. I can get close with the generic vizio model, but i need numbered HDMI inputs and I can't learn them from the TV's remote, an .mxf file would be perfect. I suppose I can get a HDMI switch and program that, as I only need 2 inputs to complete my programming, but that's another device to plug-in and manage. Thanks in advance, any help would be greatly appreciated.
