Because an old 14" CRT is dying?
Btw.: Apple has updated it's line of powerbooks. 4 out of 5 models do not
have a display aspect ratio of 4:3. ( http://www.apple.com/powerbook/ )
There are at least three options for a media player:
1. Assume 4:3 monitor
2. Assume square pixels
3. Ask X11 about resolution and size of the monitor
The first one only works with certain monitors. The second one works on
all monitors when the user has selected a sane resolution. The third one
always works unless the user writes crap into his XF86Config. All
applications I know of use either option 2 or option 3.

Some people do not exclusively use their monitor for watching movies...
If you would use (for example) a 17" CRT with a resolution of 2000x1000
pixels, option 3 would work perfectly. Just make sure that your
XF86Config contains something like
DisplaySize 286 216
(you probably already do have a "DisplaySize" entry in your XF86Config, as
otherwise fonts would have be drawn with wrong DPI)
So option 3 does not have any disadvantage (unless you write something
like "DisplaySize 286 21645" into your XF86Config) but has the advantage
that MPlayer does display movies in the correct aspect ratio.
And if someone really does not want to to have correct monitor dimensions
included in his XF86Config, he can always use --monitor-aspect...
