Here's a tip if you have a device that takes a while after
powering up to accept the next command, on your system
off Macro, have everything default to whatever inputs
and/or settings needed to use when powering up. Since
most devices are on by now, just send the input commands
before the off commands (assuming discretes are available).

eg....

tv... comp1
rcvr.....dtv
delay
tv....off
rcvr....off
dvd...off
etc..

That way you don't need long delays on start up. Just
have to send "on" commands.
