the above advise i think would apply more if you were programming the unit for a customer, where things need to be "bulletproof".

you could set it up just the way you described, whatever turns your crank. i personally have all my watch activities under watch, and my listen activities under listen. i have added a 2nd "DEVICES" page under WATCH and LISTEN with the devices that go with the macro's on the main activity pages. i also added a 3rd page to WATCH AND LISTEN with power commands for each device, so i can power up slow components (xbox 360, dvd/cd player, etc) before firing a macro.

all the best!
