Thanks for the tip, I tried it, but this parameter really backfired...

With the default "threads=-1" which uses the number of logical cores reported by Windows (4 in my case) I got a speed of 21.47 fps. Using "threads=1" the speed dropped to 15.66 fps. With DSS2Mod the speed was 24.49 fps.

After many more speed benchmark tests I can say that the AVS+ MT feature is not all that useful when using very basic AVS scripts which I usually do. The real speed difference gets obvious when using more complex scripts like the MysteryX FrameRateConverter script. This script makes extensive use of MVTools, and here I get a speed difference of almost 80%.
