Help with mencoder mpg to avi changes aspect

[Paul Ward]

Hi all,

Can anyone show me what I need to change so my converted Myth
recordings video aspect is not changed.

I currently run the following command but my video aspect changes from
I'm guessing widescreen to 4:3 so the picture is squashed.

mencoder input.mpg -ovc xvid -oac mp3lame -xvidencopts bitrate=800 -o output.avi

Any suggestions or improvements on this command would be great.
I have done a bit of googling but could not find the answer.

Thanks
