So, I think this closed captioning thing is different from case to case. Right now I'm having a situation where I get the garbled output (see below), but ONLY when using video capture cards at the same time. When they operate independently, they seem fine. Right now it's happening with two K-World BT878RF cards, but was also happening with two Winfast 2000 Deluxe cards. What in the heck does this? The picture and reception are fine. I don't get it.
Interesting -- how do you tell ntsc-cc which card to capture from?

I think I figured it out (again). Whatever program you're running while trying to capture closed captions has to be set to the correct frame rate for your capture device. I was using ffmpeg, which sets it automatically to 25 fps. All I had to do was put "-r ntsc" or "-r 29.97" in the command and it started causing ntsc-cc to behave correctly.
