MPEG2 video can flag widescreen 16x9 and standard 4x3 content in the
video stream. The AVI container format does not, so to preserve
widescreen video in AVI-based media you either need to resize the
video to a widescreen sqaure-pixel ratio such as 640x360, or use a
media player that can display video using non-square pixels,
irrespective of the actual dimensions of the video frames.
