-------------------------------------+-------------------------------------
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.
