<DIV><SPAN class=453481418-19072002><FONT size=2>This could be the problem. The
packet size from our decoder is set to 3948 - which is configurable, but I am
not sure if changing this value will upset any of the other decoders we are
using.</FONT></SPAN></DIV>

<DIV><SPAN class=453481418-19072002><FONT size=2>So what exactly is the issue
with UDP packet sizes greater than 1500 bytes? We still keep the ethernet
packets at 1500 bytes. So I don't think we are breaking any network
rules...</FONT></SPAN></DIV>

size=2>Sounds like you could be facing the same problem I was facing. Do
you know what size UDP packets your encoder device is putting out onto the
network? By default, VLC is configured to handle UDP packets up to 1500
bytes.</FONT></SPAN></DIV>
