So...Basically within mythtv you can select a tuner and when you change the channels for that tuner the proper STB is controlled ? Right, or could you elaborate. How do you switch tuners? I have never been able to get lmce to do that with the "change tuner" button from the menu and "y" doesnt work either as it does with Mythtv distro. The only way I can get it to change a tuner is to hit record on the 1st tuner and then close and reopen the TV that forces the next tuner, a little cumbersome though.
