That's great.  But in my case, my .png files are of size
325x407.  And when I use the above mencoder line, they get
encoded at CIF size (352x288) even though Mencoder says

   Writing AVI header...
   VDec: vo config request - 325 x 407 (preferred csp: BGR 24-bit)

If I explicitly include the width and height on the
command line:

mencoder \*.png -mf on:type=png:w=325:h=407:fps=25 -ovc rawrgb -o mfteszt.avi

the .avi file becomes unplayable either by MPlayer or
Windows Media Player.  Please see any message with .png in
the header for the entire thread on this.
