Now looking into issue 3 from comment #11 again.
Every time the big stutter occurs it coincides with my PC's harddisk
LED. Also, the same place in the video seems to be the first time the
stream bitrate peaks over 10Mbps. So there seems to be some kind of
cause and effect at this particularly detailed part of the video.
The stutter only occurs in totem though. No other gstreamer tool seems
to exhibit the problem when playing the same video. Even using "gst-
launch-1.0 playbin uri=file:///...." seems to not have the problem. So
all evidence at the moment is suggesting the biggest stutter is somehow
specific to the totem binary, and not gstreamer in general.
I've also just noticed a 5th source of stuttering; that is using
clutterautovideosink in an X11 session. Will ignore that problem for
now...

Bug description:
Totem pauses and stutters during video playback even when CPU usage is
low.
After figuring out how to play videos with full hardware accelerated
decoding (e.g. <= 10% CPU), I was surprised to find Totem still pauses
and stutters during playback. Other apps like Mplayer, VLC and even
gst-play-1.0 never have this problem.
