RE: Enhanced CUseeme

I'd suggest looking at modem speed. Check your baud rate within the
modem or port setting in Windows. It always defaults to 57600 even
with a 28,800 modem and I had
to go and change it to 115,200. This helped a lot. I also connect to my
NT server at work running the RAS service and I had to manually set
that to 115,200 baud. This may or may not be what the ISPs are setting
their ports at. I've tested the difference between 57.6 and 115.2 and
the bit rates in a program like CUSeeme improve dramatically. I connect
at 28,800 most of the time in the evenings (both modems are VFast USRs)
and during heavy traffic times such as business hours it may be only
24000. This has some effect on the true baud rate achieved.

All the streaming products such as CUSeeme, VDO live and Streamworks seem
to profit from this extended baud rate. In Streamworks (when the sky is
clear and all the planets align just right) I can even get away with
selecting the 56k (isdn) feeds and receive a good flow.
