My view? He can't see anything that isn't already recorded on the DVD/video track. I assume we're not talking about an entertainment show where the whole thing is a set, but maybe a video of either a crime scene or of a hostage situation or a live feed of an ongoing crime. I think Lara is right, except that the classic implicit definition of Superman's vision gizmo is that he can see beyond physical objects in his line of sight, not that his vision powers are psychic. So no, he can't see what's behind Door Number One on "Let's Make A Deal" unless he's physically in the studio. (What would he wear, I wonder?)
Of course, it's your story, and you can make him do pretty much whatever you want.
