It looks like a decent enough hack. It will still chose the
wrong video aspect ratio whenever you view a non-16:9 stream
on a 16:9 screen, but at least it will default to filling the
screen for 16:9 screens so it's an improvement. What I would
like to see down the road is some intelligent guessing as to
the aspect ratio. If we are about to view channel X and the
last time we viewed it the resolution and aspect ratio were Y,
then we should start with Y when we start on channel X. If we
are using xrandr we really want to minimize these changes.
Can you open a ticket with your hack?
