I just tried some quick tests with -mf on:type=png, and the resulting
files were unplayable for me, too. I seem to remember now, from the
last time I managed to create a "slideshow" with mplayer, that it only
works with jpegs. Also, you need to make sure all the input files have
exactly the same dimensions, or it runs off the rails. What I ended up
doing was re-scaling with ImageMagick to very high quality (and very
large) jpegs, and encoding with "mplayer ... -ovc lavc" and the
resulting avi came out looking pretty good -- the paused mplayer
window is essentially indistinguishable from the original jpegs,
as viewed with ImageMagick.

I built against png-1.2.5, so maybe that works for someone else.
("mplayer -vo png" works fine.)
