Public bug reported:

Binary package hint: xorg

Jerky playback of videos using the codec "H.264 / AVC" on a Dell Mini 9
(Inspiron 910). Totem/gstreamer skips many frames, but the audio plays.
In vlc/ffmpeg video plays for a semi second then freezes up, while audio
continues. At first, I thought that this was a codec issue (Bug #121279)
but then realized it was hardware specific when testing the video on
another machine (different video card, same driver) where it played back
perfectly.

The card which is having issues playing back this video:
VGA compatible controller [0300]: Intel Corporation Mobile 945GME Express Integrated Graphics Controller [8086:27ae] (rev 03)
	Kernel driver in use: i915
	Kernel modules: i915

The card which did not have any issues playing back this video (same driver):
VGA compatible controller [0300]: Intel Corporation 82G35 Express Integrated Graphics Controller [8086:2982] (rev 01)
        Kernel driver in use: i915                                                                                           
        Kernel modules: i915           

gstreamer-properties shows that it is using 'Autodetect' as the video
plugin on both machines. Besides that, I'm not too sure how to check if
I am using Xv or X11 gstreamer plugin.

Attached is example media for testing purposes. This clip was created
with a Canon Powershot SD780 IS Elph on HD video mode.

Codec information:
Nautilus properties says: H.264 / AVC
VLC says: AVC1
