Actually, mencoder keeps the aspect ratio as it is, but the video on the dvd
you're encoding isn't in 4:3 but 16:9 aspect ratio. With mpegs this is no
problem as it supports aspect ratios 4:3, 16:9 and (unfortunately rarely used
and supported) 2.21:1 where as avis don't have this feature. So you'll either
need to encode the non-16:9 video stream from the dvd, or use -aspect option
to squeeze (or spread, if you have a 16:9 monitor/tv) the picture to its
intended aspect ratio when playing the clip.
I'm pretty sure mencoder has an option to squeeze the video before encoding
too, but encoding the 4:3 stream from the dvd will probably give you better
quality. Should be faster, too.
