I have this recollection that the GT218 (inside a branded GeForce 210)
is just "barely" able to perform decode/de-interlace 1080i.  And as this
(newly) O&O NBC channel may have chosen to encode slightly
differently as part of the transition, you may have hit some limit with
that card with that encoding.  If viable, I would try a (gen/rev 2) GT630
or GT730 to see if the problem persists (for they are (or were) cheap
and available in low profile silent configs, if you need that).
