It's usually when an SD program is shown on an HD channel. The transfer sometimes gives you that line. I have found that using the "zoom" or "wide" setting makes it go away (it's moved up to the margin, where you can't see it).

The dotted line is analog closed captioning that is moved down into the active HD picture. Normally that line should be blanked by the downconverter at the TV station.


It's an indication that the timing of the SD signal that's being downconverted may be late compared to the HD reference signal or the downconverter is intentionally set to pass line 21.
