Yes, you're correct.  Everything is squished.  MythTV's UI parameters 
are in terms of a 800x600 window, and the graphics and coordinates are 
scaled to meet the actual window size.  If the screen is not 4:3, the X 
and Y values are scaled separately.  For some themes this doesn't matter 
much; for others (try blue sometimes) it looks just awful.

Unfortunately, some structural graphics elements (background, frame 
borders, etc.) need to be scaled like this, whereas others (buttons, 
icons, thumbnails) should really be scaled the same in X and Y.  It 
should be possible for Myth to honor a tag added to the images in the 
XML theme files to do this right.  But as for right now, the only way 
would be to make a special 16:9 theme with the images pre-distorted in 
the opposite manner (i.e. too tall).
