That's what I was thinking too.

What you did not do, though, with the optionDown, was this:
if the optiondown then
sprite(1).movieRate = 0
go frame 11 - the frame
exit
end if
You see? I mean, you didn't actually park the QT playback before
skipping to another frame. As I don't have a high rate QT file, I
can't really test this -- but what happens to memory when the QT file
is explicitly parked before you leave the frame?
Also, you mentioned freeBytes. Now a test that shows 25 Mb being used
is one thing -- but freeBytes all by itself, being used to determine
if you're losing a few extra K of space, is unreliable, since the
freeBytes test itself uses memory, as does placing freeBytes results
in the message window, which means that using "put the freeBytes"
alone will reduce your free bytes.
I know you know that, Colin, but not everyone necessarily does. To
*really* find out how much memory you might or might not be using
(and losing!) you actually need to look at values a couple orders of
magnitude greater (as you did) -- in the megabyte range.
Put another way don't obsess on a few hundred K more or less in
freeBytes. That kind of memory usage is darn close to meaningless,
background noise generated by Director itself as it operates, and
will rise and fall at intervals.
