IIRC, for watching LiveTV, the tuners are selected in the reverse order, so you
might want to consider reinstalling in the other order.
I am assuming you are leaving your box on overnight, so that would rule out any
startup problems. You might find, however, that your STB went to sleep overnight
so it misses or scrambles the first (or part of the first) IR command sent to it
when it wakes up again in the morning (mine does). You might need to fake up
some kind of dummy command that is sent to your STB when you first use it each
day, to get it into a 'ready' state.
