VSfilter.dll using 50% CPU

[AlanHK]

Any AVS script I run calling Textsub has a VSfilter.dll thread visible in Process Explorer using 50% of CPU.
Even when the script is stopped one one frame.

e.g. AviSource("Flash.avi")
Textsub("Flash.srt")

Some apps, notably MeGui, are seriously screwed up by this.

I suppose this must be a peculiarity of my own setup.
So, what is relevant?

Win XP SP3
Avisynth 2.58
4GB RAM

using vsfilter.dll from http://code.google.com/p/xy-vsfilter/ might help to lower the cpu usage

Yes, that worked.
No CPU spikes or lockup for MeGui.
The one I had was version 1.01, from 2005.

The XY version is 3.0 (seems to be successor of the original, so the version should be comparable).

MeGui had another version in its Avisynth plugins folder, 1.5, 2011 from MPC-HC.

If I deleted that, it errored out, so it appears it uses its own version for encoding. But somehow there was a conflict with the version I had in my Avisynth plugins folder anyway.

No such conflict with the XY one though.
