Followup - I tried this between two [similar] x86 desktop systems
and it worked!  It seems to only fail when my server machine is
my embedded OMAP board (running a recent kernel and the same gstreamer
modules as on the x86 systems).  How can I figure out where in the
process (pipeline) it's failing?
