We know that this is equipment related because the same program recorded from the same service provider in the same home doesn't manifest the problem using a different decoder.

I experienced different captioning results with one station, too, and learned that other people in the area with certain kinds of TVs had problems, too. The TVs that had problems decoding captions from one station were Samsung, Sharp and Sony HDTVs, whereas my LG converter box and Panasonic DVD recorder and someone's Magnavox TV didn't have a problem. Eventually the problem got fixed at the station level, though I don't know what they did.
One knowledgeable person suggested that possibly the errant station is not broadcasting the PSIP information properly, which may affect some decoding chips more than others (I don't know why). See the following topic about how some stations still have trouble broadcasting the PSIP correctly:

The station needs to make sure they have done a firmware update on their equipment (including the MPEG encoder) and to doublecheck they're broadcasting all PSIP information properly.
I know of one station that took more than seven months to fix their captioning problems; if they had simply done a firmware update on their MPEG encoder (not the caption encoder), they would have fixed the problem much, much earlier.
