FC4 may well provide a valid modeline for the monitor "out of the box"
what the symptoms you're seeing are because X-server does not know the
aspect ratio of the display. i.e. it doesn't know whether the display
is a 1920x1200 display with a 4:3 aspect ratio or a 16:9 aspect ratio.

Unless X is able to tell Myth / Mplayer / etc what the aspect ratio is
each of these programs will fall back to some default (Myth assumes a
4:3 display, whilst it appears that VLC assumes a 16:9 display).

I don't run FC so I have no idea what the default for this display is,
but it definitely sounds like you've got a modeline but no info on the
physical dimensions of the display. Also, check the archives for info
on how to set DISPLAYSIZE such that the X is working as 100dpi.
