You don't say how much bandwidth you have available to the internet.

You also didn't say how many people are connected, although I'm not sure that is
your problem, it could be a contributing factor. The more people that are
connected to the reflector, the more "static" overhead there is. By "static" I
mean that without sending any audio/video/chat, there is overhead traffic that lets
each connected user know about each other. This traffic can be significant if your
using a 28.8 modem. The White Pine reflector has some optimizations that make this
less of a problem, but it's still a problem with a large number of people
connected. Also, the 4.0B3 Cornell reflector had some bugs when running on
machines with Little Endian CPU's, like your DECstation.

I would recommend trying a White Pine Reflector and see if that solves your
problem. You can use it for free for 30 days.

Let me know how it goes.
