> I am using Matlab to make some movies of simulations I am running. There are times when the movie feature works and there are times it doesn't. When I say it doesn't work, I do not mean a  movie does not show up. All the plots show up to allow me to do screen captures to create a movie and it looks fine. The problem is that when the movie ends, no movie file is created and saved. In fact, at the end of the movie I get this error message:

When I simulate a "simple" scenario, everything works great and I get an avi file in the end. When I run something more complex, the movie craps out on me and I get the error message. However, the problem has also come up during simple simulations too. So I actually have no idea what's going wrong. I have also tried messing with the figure window size (I like to use large windows for better resolution), and that sometimes works if I make the window smaller.

Take a look at mpgwrite.dll in the FEX.
