I have the same problem as you do. I think it has something to do with the fact that you are playing a DIVX v3.11 coded film and not a DIVX v4.0 or V4.01 coded film. A movie that I coded with EasydivX v0.71 and with the latest DIVX v4.01 codec hasn't got this problem.

GdivX player you can down it everywhere...
Have fun with it!!!
