Gonk:

From the looks of things, the barrel diameter was only changed on the PCA, not the PSC. The former has the locking type connectors, but are not 75 ohm or intended for video while the latter ARE 75 ohm and intended for video. However, the PSC connector appears not to have changed and thus should remain a real 75 ohm connection. Have you seen anything to the contrary that my master may have missed?

But what do I know, I'm only a dog.
