what dvbsrc are you using? I know there was a source for GStreamer 0.8,
but I do not know of anything for 0.10.

This can be a bit tricky see other thread about pad blocking. Also try
to understand pad activation and pad modes (push, pull). It is always
well defined which pad creates the actual processing thread.

I am having a similar problem. Are you running both pipes (udpsrc and
udpsink) on the same machine? Right now, I do not have a solution.
