I eliminated all but essential options, but nothing changed. I can further try only without audio to see if the problem is related to mixing audio and video. Regarding hardware, I've said before reinstall everything was working, and nothing changed in hardware. I use libx264 and preset=ultrafast which is quite easy for my CPU. According to 'top', my CPU is 89% idle and mencoder is taking only 14% of my CPU.
