Worked for me, too, thanks, although I have to hit it twice (like many other buttons; my HR24 doesn't seem to like my TSU7000 very much, see long thread from about a year ago).

FYI, I got an HR34 and I don't have to hit any buttons twice with it. Apparently they upgraded the IR receiver in the HR34 as it is way more responsive than the HR24 and it likes the TSU7000 just fine.
