I do not deal per se with activities and pages when thinking about how the pronto functionality should be looked at. I think about what it is I want to do.
At the pronto level I prefer things as a single activity whenever possible and only use multiple pronto activities when there is just about no relationship between the functions I am trying to control.
In my world I think of the prontos by location as the locations generally define the functionality. There is a Master Bedroom Pronto, A Great Room Pronto, a Guest Bedroom Pronto and a Theater Pronto. Those names are actually where that specific Pronto lives. The xcf that goes into each of the Prontos is identical (except for the Guest Bedroom as that is a 9400). When each pronto starts it ascertains what room it is in and then starts the Pronto activity that is for that room.
The Theater Pronto is the only exception to this because the Theater is really the adult playroom and serves as a Theater, TV room, and a Music room. I will discuss the Theater since that sounds the closest to what you are doing.
The Theater Pronto has two main Pronto activities Music (SlimPronto) and the control of the Theater. The main screen (not the home screen) for the Theater Pronto allows for the selection of the basic functions Theater, Music, Games. Games is just to show off what the Pronto by itself can do and are the games others on this forum have written and contributed.
The default function for the Theater Pronto is the theater, so the Power button on the main screen will completely turn on the theater which is architected in the Pronto as a single multi-page activity. It turns on all the components that are not in an "always on" state and sets the A/V chain to the default configuration of a watching one of the two DVR's. On any other page of the Theater activity the Power button will completely turn off the Theater and return to the main page of the Theater activity. Turing on the Theater completely dims the Theater lights to off and plays a music track (Hooray for Hollywood) while that is happening. Turning off the theater puts the "house" lights back on. Every page of the Theater activity has a row of buttons on the bottom which change the A/V chain, that is connect up a different source. Once connected and powered on that source is left on unless turned off by a button on its page, or by shutting down the Theater activity.
The pronto gets feedback from the PC that it talks to which controls the theater in one case. When dealing with the movie Librarian it needs to knoiw based on the movie selected what page to put up next. This is bwcause the page for the BR player is quite different from that of the DVD changers. I have thought about making them the same, and will probably do that when I get a BR changer
SlimPronto works in a similar manner. The music player is off, the Power button turns it on. If the Player is on the Power button turns it off. If the Power button is held down for more then 2 seconds when the player was on, it turns off all players assuming that they were synchronized for a party and goes to the Theater's Main screen.
