I am trying to use the MX1000 to control an RCA S-video splitter. I have buttons setup that properly change the splitter when they are pressed. My problem is that when these same buttons are used to create a macro the RCA device is not recognizing the signal. Is ther some method to force a macro to perform the same function of "pressing a key for a couple seconds". I think the RCA device just requires a bit more time to react. I have tried "pause" commands as well as multiple key presses. None work. This is the only device in my entire configuration that I am having problems with. Can someone help!!! I'm so close to a perfect solution.
