You can call QMovie::pause() / unpause() when you are not using it.

The calls to QPixmapCache::insert() may be the culprit.
See QMoviePrivate::updatePixmapFromImage

What I don't understand is why the framenumbers keep increasing. It seems to 
me that it only has two frames or so, I would expect it to loop back frame 0. 
(But it has loop == -1 ??)

Looking at the code, Qt does not seem to realize that the mng library is 
looping between two frames and instead considers each frame a new one that it 
caches. Very inefficient.

Maybe 
	 if (!(frameperiod < 0 && loop == -1)) {
should read
	 if (!(frameperiod < 0 || loop == -1)) {

(qmovie.cpp:358)

Cheers,
Waldo
