I had some difficulties to create movies from Matlab watchable from every OS platform, even from Mac Leopard to Tiger.
I finally adopted a simple approach, not based on the movie function of Matlab but the command line function "convert".
I know this is not an amazing solution, but at least you can watch the output from everything, incorporate it into keynote talks, webpages and so on ...
> The workflow is as follow:
convert *.png movie.gif
will create an animated movie into movie.gif
> Convert is highly flexible, note that you can:
see the man page of convert
> You can also produce videos in different format such as .mov .avi and .mpg.
convert -delay 1/10 -rotate 90 *.png movie.mpg
but for mpeg compression I had to installed the mpeg2vidcodec with MacPort
