ANDRE DADE HAS YOUR ANSWER! And much to my chagrin, when I first ran across this problem with a TS1000, Daniel pointed out that it was in the FAQs.

I have implemented that method a couple of times. The first was with a JVC projector that required a 2 second button hold. I used one initial sequence followed by 11 repetitions of the repeating sequence.

Why is this different from the other things mentioned above? The initial command has some kind of ID in it to tell the unit that this is the beginning of a command. The repeating parts do not. If you just put the initial part in as a macro, over and over, the unit will not see a long command, it will see several short commands. When you string together one initial part with several repeating parts, then it looks like a button being held down.

DISAPPOINTING -- I have read that this does not work with the 7000 because that remote inserts its own delays, which cannot be removed, between commands, so the unit will not see such a macro as a long command, but as one short beginning and many incomplete commands, all separate from one another.
