Well chrome doesn't use video acceleration any way. But even so, it
should still be quite capable of decoding HD streams using your CPU and
presenting them without dropping frames. No idea about Miro. VLC the
last time I looked at it had some attrocious GL video decode pipeline
(slower and tons of artifacts).
Can you please update to raring and attach your Xorg.log?

Title:
Unaccelerated Video with installed Intel Video Card by default
Status in “xserver-xorg-video-intel” package in Ubuntu:
Incomplete
Bug description:
As far as I can work out (from performance) this machine is not using
the graphics acceleration available in the installed Intel video card.
Although xserver-xorg-video-intel is installed, perhaps there are other video
acceleration libraries or configurations which need to be loaded to benefit.
Currently, using the following video as a reference loaded in Google Chrome,
with HD turned off, and with the video embedded in the webpage (no
fullscreening)...
http://vimeo.com/44535515
...I'm getting something like 4 frames a second, which seems slow even for
this system.
My guess is that there's something not installed or not configured,
but there seem like a lot of options and I don't really know where to
start. Perhaps libva-X11-1 would make a difference? There's discussion
of Mesa, DRI and some PPAs to try like
https://launchpad.net/~oibaf/+archive/graphics-drivers/ , but I'd be
testing almost entirely at random because I don't know how to diagnose
the current situation. Happy to experiment in any direction which
makes sense.
Grateful for any help or suggestions, with the aim of being able to
auto-detect this hardware in future versions to avoid the
configuration step. Equally if there's a different way to load
internet video which loads the proper accelerations, that would be
useful to know.
