 After upgrading trunk from c9bebe8 to d27bedf, one frontend started
 playing videos with wrong aspect ratio. 4:3 videos are not affected,
 neither is live TV or recordings, but widescreen videos expand beyond the
 right and bottom of the tv screen (approx. 1/4 of the picture width is not
 visible - it's beyond the right of the screen limit).

 The pc is an Atom, the video driver is nvidia version 260.19.36., the
 display is at 1920x1080.
