Why is the output of 'movie2avi' not showing the movie properly?

I'm trying to save a movie as .avi file using the command movie2avi. The code is as follows:
b=0.3;
h=0.5;
m=2;
n=0;
x=linspace(0,b,200);
y=linspace(0,h,200);
[X,Y]=meshgrid(x,y);
F=500;
for i=1:F
p_hat=cos(m*pi*(X-i/F)/b).*cos(n*pi*(Y-i/F)/h);
surf(Y,X,p_hat,'edgecolor','none');
M(i)=getframe(gcf);
end
movie2avi(M,'p(2,0).avi','compression','None');
When I open the file p(2,0), it shows the MATLAB window that was there in the background while the movie was running.
Please help to get rid of the issue.
Thanks

Abin - are you referring to the MATLAB figure appearing in the background of your movie? As your code is passing the gcf into the getframe function, then you will see the figure (or window as you have called it) in your movie. If you wish to grab just the axes, then do
M(i) = getframe(gca);
But you will still see some of the figure because of the viewing angle of your axes (so the grey background of the figure will be present). If you wish to change the figure background colour to match that of the axes, then just do
set(gcf,'Color','white');
M(i) = getframe(gca);

Try to insert a pause(0.02) before getframe. In some Matlab versions this helped to let the screen update correctly.
