<<on my Home DVD player there is some 'shake" in the still frames and particularly in the slow motion video.>>
RodThe shaking is an interlacing issue. You can't see it on a computer screen, only on a tv, which is why it's best to monitor video work on a tv as you work.
To fix the problem in the stills, apply a de-interlacing filter to the problem clips.
