I just got a DCT700, and I ran into the same thing in doing some
testing.  I think the STB kind-of goes to sleep a little bit.  I
tweaked your script slightly by putting a couple SEND_ONCE ok/select's
at the top followed by a sleep 0.25.  This caused the STB to start
paying attention and it would then catch the first keypress.

If this is still an issue for you or someone else, maybe this will
help.   Also, much thanks for the channel change script.
