dicas mpegable MPEG4 Decoder

I've got 30000frames length clip from my recent SPR backup (XviD1.0 RC3 BFRAMES=YES, GMC=NO, QPEL=NO, 576*320). It's part of beach episode (heavy motion and details). I assume fps=180 in order to decrease overall test time duration.

For each decoders listed above I create such graph into graphedit:
[Clip]->[AviSplitter]->[Decoder]->[Null Renderer]
I disable any PP into all decoders and play those graphs. When playback finished i used Windows Task Manager to estimate Decoding CPU Cost in form of CPU Time. I've got such results on my AthlonXP2000+ 512RAM WinXP Prof SP1:

mpegable ~ 200sec
ffdshow-20040405 (XviD 1.0 for decoding) ~170sec
DivX ~156sec
3ivX ~155sec
XviD ~154sec
NeroDigital ~145sec
ffdshow-20030523 (iDCT=XviD) ~104sec
ffdshow-20030523 (iDCT=simple) ~103sec
ffdshow-20040405 (iDCT=autoselect) ~94sec
