While I can only assume you're actually playing that video, you
shouldn't be able to on that chip. The Atom puts out about half the
work of a Core2 per clock. I came across a review and benchmark on
AnandTech
(http://www.anandtech.com/systems/showdoc.aspx?i=3321&p=4&cp=4) which
found a limit of around 4.5Mbps. This was on Windows, and the board
offers no hardware acceleration that Windows could take advantage of,
but I cannot believe you could get significantly more performance in
linux, much less double.
