Bizare behaviour with RTP mpegts sources

Summary of the bug:
I'm transcoding a bunch of SD sources from SPTS mpegts transported on different multicast addresses with RTP on port 5530. (VBR h264 video, mp2 audio)
When I transcode the first source from mcast IP1:5530 the output is sort of OK (occasional green patches and false reporting of unsupported source features)
Once I run a second ffmpeg instance to transcode source IP2:5530 the second instance is not ingesting IP2 content but IP1 and both instances start to interfere and they don't even come to a state to start transcoding.
It's bizare that even two ffplay instances tuned to different sources play back the same content!
I tried playing back with vlc and there is no such problem.

Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.
