Robert,
	what I usually do is to plot my plots as png (or ps and convert it to 
jpg) then I use mencoder (http://www.mplayerhq.hu) to create an avi movie:

mencoder \*.jpg -mf on:w=1124:h=638:fps=1 -o output.avi -ovc lavc 
-lavcopts  vcodec=msmpeg4v2:vpass=1 -nosound -oac copy
mencoder \*.jpg -mf on:w=1124:h=638:fps=1 -o output.avi -ovc lavc 
-lavcopts  vcodec=msmpeg4v2:vpass=2 -nosound -oac copy

I use two passes as this way the output.avi is smaller.
