    MPGWRITE Write an MPEG file.
    	MPGWRITE(M, map, 'filename', options) Encodes M in MPEG
    	format using the specified colormap and writes the result to the
    	specified file.  The options argument is an optional vector of
    	8 or fewer options where each value has the following meaning:
    	1. REPEAT:
    		An integer number of times to repeat the movie
    		(default is 1).
    	2. P-SEARCH ALGORITHM:
    		0 = logarithmic	(fastest, default value)
    		1 = subsample
    		2 = exhaustive	(better, but slow)
    	3. B-SEARCH ALGORITHM:
    		0 = simple	(fastest)
    		1 = cross2	(slightly slower, default value)
    		2 = exhaustive	(very slow)
    	4. REFERENCE FRAME:
    		0 = original	(faster, default)
    		1 = decoded	(slower, but results in better quality)
    	5. RANGE IN PIXELS:
    		An integer search radius.  Default is 10.
    	6. I-FRAME Q-SCALE:
    		An integer between 1 and 31.  Default is 8.
    	7. P-FRAME Q-SCALE:
    		An integer between 1 and 31.  Default is 10.
    	8. B-FRAME Q-SCALE:
    		An integer between 1 and 31.  Default is 25.
