Unfortunately still no improvement. I'm tempted to believe the packets 
are being dropped by the stb nic before they're read by the kernel. Is 
there anyway to test this?

You are absolutely correct, however after weeks of trying everything I 
can think of, reading way more than anyone should on the issue, and 
posting to the MVP forums I'm still in exactly the same position 
(10-14% overruns RX errors). I'd like to get to the position of 
successfully playing a DVD between my server and client on my LAN. 
Perhaps by releasing a working version to the MVP & Live.com 
communities someone might solve the client buffer overrun issue where I 
have failed.

If I was to look at smoothing the video packet bursts from a server 
written using the live.com libraries (say 
testMPEG1or2AudioVideoStreamer), any ideas of where to start?

Thanks again for all your help
