Yup, it's interlace you're seeing.  3:2 pulldown from 24fps source
interlace, to be specific.  For comparison, record a local news
broadcast (preferably one that has *not* gone hi-def yet), and frame
through that.

Deinterlacing *can* help, though I don't know precisely which mode will
work best for you...
