[MPlayer-users] VOB aspect ratio mystery

Hi,

I'm wondering about how mplayer is performing some magic.
I've a MPEG2 VOB with a 4:3 (aspect 2) encoded in the sequence header.
This VOB is actually 16:9 and mplayer figures this out somehow,
and prescales it correctly. Specifically the version that does
this on my fedora 8 laptop is:
MPlayer dev-SVN-r26936-4.1.2 (C) 2000-2008 MPlayer Team
which if packaged as: mplayer-1.0-0.91.20080531svn.lvn8

I had an older mplayer on ubuntu breezy that didn't notice
it was 16:9 and played it squashed:
MPlayer 2:1.0~rc1-0ubuntu13 (C) 2000-2006 MPlayer Team

So I assumed it was new code added, so I downloaded the
latest as shown below, but this doesn't notice it's 16:9 either?!
MPlayer SVN-r28525-4.1.2 (C) 2000-2009 MPlayer Team

So what's the first version above doing that the others aren't?

cheers,
Pádraig.

p.s.
I just downloaded and built this:
http://www.mplayerhq.hu/MPlayer/releases/mplayer-export-snapshot.tar.bz2
But that showed an old copyright year??
MPlayer SVN-r28519 (C) 2000-2007 MPlayer Team
