movie2avi - I am getting a blank movie, but no errors.

When I make the movie, it plays fine while I'm running the code. When I run movie(M), it gives me a weird off-center axis and movie2avi(M,'somename.avi') is just a blank screen of the proper time.
Z = peaks;
surf(Z);
axis tight
hfig=figure;
xlabel('x');
ylabel('y');
zlabel('z');
xlim([0 60]);
ylim([0 60]);
zlim([-10 10]);
M(1)=getframe(hfig);
for k = 2:200
surf(cos(2*pi*k/50)*Z,Z)
zlim([-10 10]);
M(k) = getframe(hfig);
end
Any help would be great. Thanks

You might need to add a pause() for a short time before the getframe. You are not supposed to need that, but in practice some people need it.
Also, before the first getframe() you should
hold all
and change your graphics code slightly. Easiest for me to show you:
Z = peaks;
hfig=figure;
oldsurf = surf(Z);
axis tight
xlabel('x');
ylabel('y');
zlabel('z');
xlim([0 60]);
ylim([0 60]);
zlim([-10 10]);
hold all
pause(0.1)
M(1)=getframe(hfig);
for k = 2:200
delete(oldsurf);
oldsurf = surf(cos(2*pi*k/50)*Z,Z);
pause(0.1)
M(k) = getframe(hfig);
end
hold off

All movies, or just one particular movie? Could you upload the movie somewhere?
