why this fps drop and how to fix it?

Hello peoples,
I've got this problem. When I load the following patch
and I load 8 movies in 8 different jit.qt.movie's,
then my frame-rate is dropped way too much.

at the moment I delete the last 7 jit.qt.movie's and let only
the first one (the one that is actually doing something) working,
I have a normal fps again.

most strange thing: sometimes when I open this patch, it IS actually
working as I exptected with full framerate. completely random!

How is this possible, there is only 1 movie running at a time.....
How to fix this? what I want in the end is a way to smoothley switch between
8 video's which has been preloaded.

thanks for any help!

There is a nice example of using poly with video that might be useful:

thanks!:) that made me indeed understand what I did wrong.

very simple: not sending bangs to a jit.qt.movie is not enough to
keep him out of the cpu. You also need to send a "stop" message.

that's all :)
