James, you're fundamentally misunderstanding what you are seeing.
If you have a 4:3 picture fullscreen, it is using (presuming you are
in the US) 704 x 480 pixels.
If you pillarbox this and present the entire picture as anamorphic
widescreen, the 4:3 picture in the centre, plus the pillarbox bars on
the edges, are still occuping 704 x 480 pixels - the pixels are now a
different shape. However, the 4:3 picture itself is now only 529 x
480.
So in fact this is *decreasing* the resolution of the picture compared
to encoding it as 4:3 proper.
There is a second problem here also. If you have a 4:3 TV and a DVD
player set to letterbox anamorphic DVDs, the 4:3 picture on these
discs will be presented as 'postage stamp' - ie it will be both
letterboxed and pillarboxed rather than filling the entire screen.
