I just reinstalled my entire box and at this point my biggest problem is getting the USBUIRT to change the channel on my STB. I've enabled the USBUIRT to control set top box in the configuration, trained it, and verified the channels are set to external. I can even use the test function and it will successfully change the channel every time. However when you change the channel in MediaPortal it won't change the channel on STB. It doesn't even try sending a signal.
