Right, so trying to mash a 4:3 image onto a 16:9 display is just stupid.

It varies, and some DVD players let you output widescreen in which case
the dvd player will simply remove some of the black bars on a wide screen
movie.  I believe the movie is actually sotred widescreen without the
black bars at all, and the correct aspect ratio is stored in the data and
the DVD player adds those bars on playback depending on its configuration.
