<DIV><BR></DIV>One way to tell what is going on is to mute all of the
video streams. when muted, all vic is doing is parsing the packet
streams, and not decoding the h261 (as I recall anyway). It is
definitely not rendering them. If you still see frame loss with streams
muted, it is most likely the network at fault.<BR><BR>You can also bring
up the CPU monitor; if you are seeing 100% CPU with the video streams
being displayed, that's a clue that the computer is not keeping
up.<BR><BR>--bob<BR><BR>On Feb 21, 2005, at 8:45 AM, Natalia Costas Lago

have quite a huge problem. VIC is performing in a strange way, I have
13 windows on my display and each videostream has been reduced its fps

something like
that.<?/x-tad-smaller><?/smaller><?/fontfamily></BLOCKQUOTE>
