So I'm using an old 5.4 IR remote with one of my Joey's, because I have the HDMI going to 2 rooms. The remote works good, but I can't figure out if there is a way to send the Red, Green, Yellow and Blue buttons. I see that the Rewind, Back, 30 second skip, and Forward, are colored as if I might be able to use them for these keys. Does anyone know if there is some type of sequence for this?
