Matlab movie problems

I have just copied the following code from the matlab instruction manual:

    figure(1)
  numframes=16;
  A=moviein(numframes); % create the movie matrix
  set(gca,'NextPlot','replacechildren')
  axis equal % fix the axes
  for i=1:numframes
     plot(fft(eye(i+16)));
     A(:,i)=getframe;
  end
  movie(A,10,3)
  save movie.mat A 
  mpgwrite(A,jet,'movie.mpg'); 
  unix('mpeg_play movie.mpg') % Play the MPEG movie

I get the following error:

??? Undefined function or method
'mpgwrite' for input arguments of type
'struct'.

Error in ==> movie3 at 12
mpgwrite(A,jet,'movie.mpg'); % Convert
the movie to MPEG format

I am using a Mac OS C 10.6.6 Intel version. Thanks

Can you provide a link to the "instruction manual." There is a FEX submission mpgwrite, but I cannot find any documentation on an official Mathworks mpgwrite. You might want to try VideoWriter
