The only meaningful advice you'll get is from the people running the show. They may have very definite ideas about what they want - or they may have the common attitude of "whatever."

The advice to "focus on someone in the audience" is generally because it helps the performer feel like there is some contact. I doubt that you'll get that feeling from looking at the little red eye, and - especially if you have never done TV before - lots of folk have a tendency to "freeze up" looking at either the lens or the red dot.

Most TV viewers watch as "voyeurs." They expect to see something in which they don't really participate. Only if you are "the only one important" (for the moment) in the act AND if your song is one that can be construed as reasonably directed to a single "target person" who will take it personally - then emulate "eye contact," in what ever manner the production people recommend. Otherwise - do your act just as you would before an audience - pretending that you're focusing on someone where the audience would reasonably be.

A "trick" related to me once was to take a "program consultant," and inform the crew that you'll need to look at him/her occasionally during the performance - for cues(?). Ask them where your consultant should sit. Then don't giggle when your "consultant" makes faces at you.
