Hi Douglas!
Silly me! I was checking the QTMovieView instead of QTMovie itself.
It works fine now. However, I don't understand *why* it works. I use
the following:
QTMovie *myMovie = [myQTMovieView movie];
[movie setRate: X.0]; //whatever rate
And it instantly takes effect. I don't understand how I can create a
new instance of the movie, modify that, and then the movie that is
currently playing accepts the changes. I would *think* that I would
have to follow the code with a [myQTMovieView setMovie: myMovie]; but
I dont.. It "just works"...
Thank you
AA

Check the documentation, under "Setting Movie Attributes" you will
find two methods to help you accomplish what you want to do. Use
either -setAttribute:forKey: to set a single attribute or -
setMovieAttributes: to set several attributes at once. The keys
(listed under the "Constant" link) you want to set are
QTMovieRateAttribute or QTMoviePreferredRateAttribute or
QTMovieRateChangesdPreservePitchAttribute (depending on what you
"really" want to do).
