Hi Tim, 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.

I have tried the 1080p and 480p H.264/mov version and they seem to play fine for me with gst-launch-1.0 playbin uri=file:///path/to/foo.mov and 1.0.3 and git master. (Your hand-crafted pipeline would probably benefit from a queue before the xvimagesink.) Is it supposed to be very noticable? Or does it only happen after a while (I watched only the beginning)?
