Stuttering might be the frame rate depending on what it's affecting. At 10fps, there will be gaps between each recorded frame. The length will depend on light conditions (and thus shutter speed). Don't know if you can set shutter speed independently in BI.
Whilst that 10fps is fine for pedestrian prowlers, if you're looking at a faster moving object eg a speeding car, it can have travelled some distance in the time between frame captures, which results in it appearing to jump or stutter down the road. To put it another way, at 10fps each frame is potentially 1/10 of a second in duration or 0.1 seconds in duration. Apart from the fact that the shutter is probably faster than that. At a 1/50th second, each frame will be (if my maths is correct - it's late at night here and I'm tired), 1/5th of 0.1 seconds = 0.02 seconds in duration. Between each frame therefore, 0.08 seconds goes un-captured. Any significant movement of an object during the period when the camera isn't recording will result in a visible jump of the object or stutter, as it moves down the road. That is why motor racing videographers etc. don't set overly fast shutter speeds. There's also the rule of setting the shutter at 180 degrees. A slower shutter helps reduce the interval between captures at the cost of a little blur.
Not saying it is this, but just be aware. Example here (bear in mind this is probably shot at 30fps):
You can see how a faster shutter = more gaps between recorded frames, starts to introduce stutter and this is most probably at 30fps, not 10 fps.
If this isn't you problem, have you checked your pc specs and tested it's performance? There might be a processing or read/ write issue.
