[MPlayer-users] Changing aspect ratio in AVI file?

I have a couple of avis which have 512x384 resolution, but aspect ratio
says they are 1.77:1. No problem on my PC, but on my DVD player it is.
Mplayer -v -frames 1 output is attached.

I tried fixing this with mencoder -oac copy -ovc copy -force-avi-aspect,
but it didn't help with my DVD player, it still gets the 16:9 aspect from
somewhere. From the docs it looks like this -force-avi-aspect affects
something that only Mplayer supports? But what does my DVD player use
then? The player is a Pioneer DV-575, I believe it uses the commercial
DivX decoder.
