I was having what looks like interlacing problems with a recording I'd
done (via a Canopus ADVC-50 and dvgrab, for reference), so I performed
the test described in section 3.4.3 of the HOWTO.  Now, according to the
HOWTO, I should have seen groups of two nearly identical subframes; what
I saw instead was a group of two followed by a group of three, and
repeating two-three-two-three, with obvious combing effects in places.
As a reference sample, I've put up some of the subframes from the test
at:

                             .
                             .
                             .

Is this the infamous 3:2 pulldown I've heard so much about?  I thought
that only happened with movies converted to TV; but this is a TV show I
recorded (indeed, after further exploration, I found similar effects
even in the commercials).

The question, then:  is there any way to fix this?  yuvcorrect doesn't
seem to have an option for this.  For 3:2 pulldown, the HOWTO suggests
yuvkineco -- what does that do exactly?  What really worries me, though,
are the subframes that look like they got changed halfway through, like:

I wouldn't doubt there's no way to fix things like this.  TIA, at any
rate.
