yes. and why are you so surprised? windows dlls are poorly optimized,
compared to ffdivx or divx4linux. and they use yv12 while dll's do internal
yv12->yuy2 conversion too, and so require 1.5 times more bandwith.

> IMHO it occured after that when there was changed C++ stuff with C one for loader subdirectory.
no. results were the same with c++ too. you wrote that 0.50 had the same,
and it used c++ version... btw, try teh vfw codec dll, it has teh same speed
and it never used any c++ code.

but again, libavcodec is faster than win32 codecs from the beginning, and
faster than divx4 for some months ago.
