Comcast box suddenly stops controlling...
I am controlling a Motorola Comcast STB with AMX, and after working for a number of days, all of a sudden, in the middle of scrolling through a menu, control stops. I checked the program, the IR file, the AMX emitter (I can see it flash with my cell phone), emitter placement, ran the IR on a different master, etc, and nothing worked. What's weird is the Comcast remote still works, so the STB still seems to be controllable over IR, but not through the AMX system. Even recopying the remote's IR using IRIS and reloading it doesn't work. Perplexing. In what case would the STB work with the manufacturers remote but not the same codes with an AMX IR emitter? I tried various timings with IREdit, and I can't even get the STB IR LED to flash that it received a command. Makes me think the STB is faulty, but since the remote still works, I can't be sure.
