Maybe you get that idea from encoding to MP4 ?
When encoding to MKV the display aspect ratio (DAR) is defined in the
container, the resolution of the video stream can be anything.
MY preference is to use the full resolution (720x480) of the source in
the video stream and adjust the DAR in the mkv. I COULD use 640x480 in
the stream but I would be discarding resolution with only a slight
reduction in bitrate. I prefer to maintain the maximum available quality.
My encode, my preference. Nobody has complained up to now.
This choice is a lot more significant when I get to widescreen 16:9 DVDs
where I can still encode at the maximum available resolution of 720x480
or 720x576, with DARs of 852x480 or 1024x576, rather than cropping down
to 720x400.
