Recently, I've been frustated with MATLAB's movie making capabilities - it generates HUGE avi's or avi's with fairly horrible quality compression.

Best solution I've found is to use ffmpeg, a freely available mp4 encoder (among other things...) A version for windows is attached to this page.

In MATLAB, the commands to generate a movie are then:

max_time = something;
FPS = something;
timeframes = floor(max_time*FPS)+1;
h = figure();
videoname='test video';

for i=1:timeframes
    F(i) = getframe(h);
    time = time + 1./FPS;
clear F
!ffmpeg -i test.avi test.mp4
!del test.avi
you just need to ensure that ffmpeg is in the windows (not Matlab) path...

I've also had some issues with these movies looking funny in Windows Media Player (the colors were offset from their intended positions...) This may be a codec issue specific to me, but using Quicktime instead works fine.
