cannot open two videosinks for two programs of mpegts

Hi Peter.

Nevetherless I can open each stream smoothly with one of one program pipeline, when 
two streams is going on.

I don't see any problem with udp. PIDs are different for each stream, continuity counters are
different for each PID. So they should be easily separated by tsdemuxer.

But why two tsdemuxers cannot work in one pipeline?
