I get the same.

I've tried to debug open_stream in MHEGBackend.c and I've noticed the following:

Usually audio & video go together and open_stream is called to open the dvr for audio and video.
In the news multiscreen page, first the dvr is opened for video (no audio) and afterwards it is 
opened for audio.

This is *not* possible. For some reason the dvr can be opened only once.

The problem is that I cannot figure out how you it can work for you. I've noticed that the code 
follows a different path if it runs on the same machine as the server. Are you running over the network?

There are 2 possibilities in my opinion:

1) treat dvr as a singleton and share it
2) use the new feature DMX_OUT_TSDEMUX_TAP

where the demux outputs TS data (the same as DVR) and not PES (as it used to do).
