Hi Matt,
Could you please elaborate as to what you mean by 'TMM registration'? Other than making sure that the RTX license is installed there should be no other specific interaction needed from TMM, especially as the application you are using, to the best of my knowledge, talks to the receiver directly using TPSDK. I do remember that your app had a setting for RTX-IP or RTX-SV, and we did talk about the developer adding an 'RTX-any' option, is it possible there is some interaction there?
Feel free to reach out to me directly.
Best regards,
