hi

i didn't see anyone mention this yet, that vic and rat use the even port number
you assign them plus the next higher one (odd); i know this is true for
multicast, not completely sure if it's true for unicast or not, but i suspect
so. therefore, 2 adjacent ports per stream (either audio or video).

I am trying to connect up to my venue which only has one camera feed.

I've seen it max out at 450 bps --> = 56Kbs

So that's why I feel my 1Mb connection is sufficient.  And I was thinking it
was a port issue.

So far, all I've got is one port that has to be open for audio to come
through, but the only thing that currently comes through is text when it is
type in the venue.

Also, is it planned in a future relase to timestamp notices in the venue?
Such as Victor Babson entered the Venue at 11:20 am.

Thanks again for all who have replied.
