I have now tried the trunk version of mplayer and I can say that the
problem is much less but it is still there. xine and vlc plays the
streams fine so I think the problem is still in mplayer.
I can make the files available if anybody cares to have a look. They are
encoded by a Tandberg encoder and streamed with a Tandberg IP-streamer.

Out with -identity from the content that is the most blocky:
