Hello,

If you have an MPEG-2 plugin with IPTV or some other similar viewer,
please check out:

I'm also trying to get an MPEG-1 stream working with a vbrick.  I can't
seem to see the SDR in my content manager.  I tried using RTP and it was
crappy (sync problems between audio and video streams) and I see that
other sites with vbricks are using the UDP mode with a single MPEG system
stream so I've set that up but can't seem to get the SDR announcements
to be seen by IPTV content manager. It shows up on my router though:
