You haven't said exactly what codes you stored to turn on the receiver and select video2, but you may have used POWER (a toggle ON/OFF key) and then VIDEO. It's possible that VIDEO by itself would turn on the receiver. If VIDEO works this way your macro is turning the receiver off and back on again. You could (should?) use a separate macro to turn everything off, and program it without the VIDEO button. (Are you aware that you can put macros on nearly every key, not only on the 4 buttons the manual mentions?) Maybe Shift S2 would be good for turning things off.
