Hello Chris,
We ran a packet trace and everything seems to be normal. The server sends
data to the client and then somewhere halfway through, the video stops but
the timecode keeps running. When the client comes to the end of the movie
(timecodewise), the client sends a message to the server. Nothing in
particular happens when the video stops playing. From a network traffic
stand point, it appears as if the movie played back successfully.
We have also been testing peer-to-peer with no firewall with the same
results. We have been unable to recreate the problem on other systems. The
system we are using is a clean install of Windows 2000 server, DSS and VNC
for remote control. Other than that, there is nothing else on the server.
Our systems administrator seems to think it's a problem with DDS on windows.
Have you heard anything like this?
Thanks for your help,
Jeffrey Jousan
