Playback problem with big_buck_bunny H264 .mov

It is noticeable all over the movie and the first scene when the cam pans
down to the meadow is not more than 5 - 8 fps - no fluid motion. It might
get better after few seconds but it is never perfect so if you did not see
any problem there might be something wrong with the ubuntu ppa version as I
can reproduce it on two notebooks with very differnet HW.
I'm using that movie for benchmarking and testing as its free and quite
demanding on the decoder. Not every video player can play it well for some
reason. For example Samsung TV has noticeable artefacts and goes out of
sync 3x in the movie.
