dimensions given to -mf are ignored since ages...

-vop scale has a second function along scaling: colorspace conversion.
maybe your jpegs are same size but different colorspace - maybe you don't
even notice but teh jpg compressor changes y/uv resolution or just use
greyscale mode for dark images to save space.
i'm trying to workaround it in vd_ijpg but it wasn't really tested.
i need sample jpeg sequence triggering this.

anyway teh last gdb log you or someone showed about mencoder -mf crash was
about the osd rendering - dunno why as that code should not be used by
mencoder unless you render subtitles over the images.
and it shouldn't crash even if you want osd...
too bad that i can't reproduce it :(
