Heavy data stream from Reflector, but no picture

Hi all,

I got a few questions about Reflectors. Bytheway, is there a sepparate
mailing list for reflectors? If so, whats it called?

I am using the latest Windows cu-seeme, with Trumpet Winsock 2.0b.

I am on the end of a 28,800 bps + compression leased line to the Internet.
In case of cu-seeme I think I get a througput of about 35 kbps. I know,
ce-seeme is not designed for these low lines (something which I think should
be addressed...)
The problem is as follows. I connect to the Cornell Reflector.
I see 3 transmittors and 3 lurkers. Only one picture seems to do something,
so I *close* the other 2 windows, and I only leave one video window open.
After the initial (partial) buildup of the video window, the transmission
speed drops back to 0 (zero). The picture is not furter updated, and often
is not complete. At this time, my leased line backbone is completely and
totally swamped with data. The modem is smoking. It is so bad, I get errors
in the updates of my routing tables, as the routers have no room left to
transfer routing information over the link in time.

So, while all this extremely heavy traffic (more then 30 kbps constant) goes
on, my only open video window stays un-updated, with a transfer rate of zero.

Now my question is, what the hell is the Reflector sending to me?????
I get the impression that there is a *massive* overhead on 'internal'
Reflector information being transmitted, so bad that people with low speed
links have no room left for the actual video!!

Also, when I close a video window, I *do* hope that the reflector stops
sending my video information for that window?!

I would like to ask the developers of the Reflector software to try and cut
back on any non-video related overhead. I get the impression that 'list
information' is being send all the time, even if there is no change in the list.

Am I the only one with these problems? Or has everybody else a T1 link to
their computers..?

Any input on these questions welcome!
Also, where can I read how the Reflector software works? Is there a RFD for it?

Cheers, Bart
