urgent problem in udpsrc

[Chuck Crisler]

OK, so this is about the simplest, most reliable plugin, and it is failing.
Clearly the plugin isn't at fault, but something in my system is. The
pipeline is:

udpsrc port=$1 typefind=true !
'application/x-rtp,media=video,payload=96,clock-rate=90000,encoding-name=H264'
\
    ! rtph264depay ! video/x-h264 ! ffdec_h264 ! ximagesink sync=false

I am running on a brand-newly created VirtualBox VM RHEL 6.3. Gstreamer
0.10.30, good-plugins version 0.10.25 running. This is one of my standard
test scripts that I can always count on, but most of my work is on CentOS
6.0 and not in a VM. Regrettably, I don't have an option here. IPTables is
off. Does anyone <PLEASE> have any ideas what to look at to resolve this
problem?

Tia, Tia, Tia
