I see.
I tried raw recording before, but it seems I was confused by FPS Override menu item description at the bottom, which said "changes FPS, also disables sound", and somehow did not notice that I also had to turn Mlv_sound on in the audio menu, just activating the module was not enough. Yes, it does work with raw video, tried to record at 6 FPS and it seems to be fine. The only thing is a warning "crash detected" just after starting to record, but video file is recorded successfully.
So thanks a lot for the response.
