[MPlayer-users] Aspect ratio with .ogm files?

[Adam Nielsen]

Hi,

I've been encoding some broadcast TV into XviD, and I'd like to create ogm 
files out of them, but because the broadcast video is a 4:3 program in 16:9, 
once I've chopped off the black borders the resulting video is squished 
horizontally to 528x560.

So rather than stretch the video horizontally, I'd rather encode it as is and 
have mplayer stretch it back out on playback.  At the moment I have to use 
the -aspect 4:3 option to do this, so I was wondering whether mplayer 
supports any other flags in either XviD or ogm files that can make this 
process automatic.

Thanks,
Adam.
