mplayer is changing aspect ratio
I have some tv episodes that have an aspect ratio of 4:3. When I play them with mplayer it is changing the aspect ratio, so it is leaving me with a stretched image, According to the output, it is changeing the ratio with prescaling, that seems to be the problem, but I am not really sure. Below is the output
