It sounds like your xorg.conf is missconfigured. You must tell
Xorg what the display's physical aspect ratio is as appears
it can't query this from the hardware. Once X knows that,
MythTV will know that the pixels are not square and will adjust
accordingly.

If you are using multiple displays and using a Xinerama to
span the screens you need to tell MythTV the aspect ratio
of the display which will be displaying the video, this is
in the frontend configuration.

Now that you know the basic problem, search the users mailing
list, this has been discussed there a few times.
