Hi, can anybody help me to find out what's the reason for the error below?

Symptom
===============================================
In our system, a local HTTP server object is initialized to receive the WMV
streaming data from outside Internet.  It then forwards those data to a local
Windows Media Player(WMP) ActiveX object which is initialized to receive and
play the streaming data.

The mechanism above works perfectly when the streaming bitrate is low
(300-700Kbps). However, if the bitrate is above 1Mbps,  after a
certain period of time (20~40 minutes) while the WMP object can keep
receiving the streaming data from the HTTP server object, it cannot
play the data properly (image frozen).

When we do debugging, we found 7 threads in the WMP object aborted. My
question is, what are those 7 threads for? Can anybody who knows MWP give any
clue? Thank you so much!
