An easy workaround is to write an mplayer config file for the movie and 
put "aspect=1.78" in it. The details are in the "GENERAL NOTES" section 
of the manpage. Though this is MPlayer-specific, setting the aspect in 
the MPEG-4 video stream (AVI doesn't store aspect) probably doesn't work 
for other players either. Even ffdshow (a Win32 DirectShow filter using 
libavcodec) doesn't respect the aspect value.

As long as you plan to play a movie with MPlayer, you can do all kinds 
of cool customization using movie-specific config files.
