<DIV><FONT face=Arial size=2>Hi everybody,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I 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 rate. It seems like VIC discarded frames due to performance
issues or something like that.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any help about this will be greatly
appreciated.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Kind regards,</FONT></DIV>
