MythTV uses the X configuration to find the aspect ratio of the 
display.  You need to configure X properly to use a non-square 16:9 display.

and, especially,

(And if you're using Xinerama or similar, you'll have a Monitor aspect 
ratio setting in frontend settings under Appearance Settings that must 
be specified properly.)
