But SD LCDs are pretty rare.  Most people with LCD TVs are going to
have higher resolution display (720 lines at least).  The display is
going to be scaling the image digitally to fit the actual number of
pixels it has and if all that's available is an SD signal, an
anamorphic encoding will give the display the most information with
which to create the picture.
