My wife just got a Mi Box (I think it's version 4). We use a Home Theater Master MX-500 Universal learning remote to control all our home theater components. I've tried to program in the functions of the Mi Box, but while the MX-500 says it's successful in learning each button, when I try to use it later, the Mi Box does not respond to any of the buttons from the universal remote. I've used this remote for many years through many different components and I've never had a problem with it learning from the other device remotes before. While I've changed the Mi settings to get the English UI, there are several areas that are still only in Chinese. Is there something else I need to do to use a different remote control? Is there something different about how the Mi Box does IR commands? I really don't want her to have to use 2 remotes to watch this thing.
