Hi,

I think there were a few things but the one I remember was that vic does not buffer its output frames, so that it can cause packet overflow on the Polycom.

I am fairly sure that the polycom should work with the vic replenishment algorithm as this is pure h261 (it skips blocks and macroblocks, but this is fine by the h261 spec).  I could be wrong though...

Andrew :)
