I've upgraded my ffmpeg version to 0.11.1

The result is unfortunately the same as before (still a lot of pixel errors
and interrupts every several seconds).

The "-r" doens't fix it.

With the new version also comes another problem: The Stream-Numers (#0.0,
#0.1,...) don't keep the same input-connections (so that #0.0 sometimes is
the video-stream, but sometimes #0.0 is one of the audio-streams)???

Here's the output:

ffmpeg -i rtp://@239.35.10.4:10000 -map 0:0 -map 0:2 -vcodec copy -acodec
copy -t 30 -y -r 50 test_r30.mkv
