It might help if you play with the 
"DisplaySize" attribute of X,
in my xorg.conf or XF*4 file 
I have

----------------------------------
Section "Monitor"
        Identifier      "Generic Monitor"
        Option          "DPMS"
        HorizSync       28-38
        VertRefresh     43-72
        DisplaySize     400 225
EndSection
-----------------------------------

Which as far as I can detect is correct
(for movie playing) on my 16:9 television.

Then I force the aspect some more in the
myth configuration (aspect override).
