[AG-TECH] "waiting for video" with unicast

sorry for resurrecting a dead thread.

since VIC uses different source and destination ports, how does one figure
out what the source port is or vise versa?

i have a bridged Venue server ?receiving? video unicast on port 56000.
(/usr/bin/QuickBridge -g 224.2.211.9 -m 61339 -u 56000).
what port would the unicast Venue client VIC be ?receiving? video on?
would VIC be ?sending? video out on port 56001?

the ??s mean that i'm not completely sure if i should be saying
'sending' or 'receiving'.

thanks.
