This is probably not a "handshake" problem as much as it is a quality
problem. If you're on a reflector that's NOT MPCS, the quality for color
needs to be around 20-25% for people to be able to see you. If you saw
data coming in from them (the kbps on the window fluctuating), then this
is most likely what it is. Ask them to lower their quality down. The way
I've seen all the color codecs work is by sending a complete frame. If
the frame size is big enough (ie: high quality), then it will take quite a
long time to receive any vid from them.

MPCS seems to handle higher quality vid much better though...you can send
using 50-60% quality on a modem and still be seen by others.
