i set thread auto to x264 (options supported), but with xvid the standard mencoder build seems lack support...better, even if i set thread to 2 (thread=2) is used inly one core and the other is near sleeping (~30% usage)
i tryed downloading lates celtic druid build and the result is near the same
also upgrading the vfw build of xvid has nothing to do with xivd 's mencoder
i will search some optimized mencoder build...
