I'm currently using 5000, which is a compromise between block artefacts
and stutters on high bitrate scene in some videos. Look at scenes with
rapid movements or zoom outs.

Actually, with 9000 most videos play perfectly smooth - there are just a
few, that have scenes where the video gets choppy. What is remarkable
about that is, that my P4 2.4 GHz system has only a load of 75% or even
less - so there should be plenty of computing power left. It looks more
like a problem in mplayer, as the results change to the better if I
disable mplayer's caching.
The bitrate of the original divx videos is independent of this problem,
meaning:
A video with a high bitrate might play smooth whereas a video with a low
bitrate is choppy at scenes with fast movements (e.g. zoom out).

I think, everyone has to find the optimal value for his individual system
for himself.

Cheers,
Juri
