"Ver" means 'to see' and it would be followed by "a" IF the thing being seen (direct object) refers to a person. This extends to anything related to people, such as 'somebody', 'nobody' and a few other sayings that relate to people, or the presence or absence of people. Curiously, it can also extend to pets, which I guess are considered to have people-like qualities. In other instances, "a" is not used.
Sonia's comments on "va" start at 2:09, and then she talks about "ir" immediately follow at 2:29. "Ir" means "to go" which usually has a direction associated with it, and it can also be what I think is called an auxiliary verb. So, examples of "ir" verbs would be "Ella va al mercado" (She is going to the market) -- directional, and "Yo voy a escribir una novela" (I'm going to write a novel) -- auxiliary. These both require "a". I wonder if you thought she was still talking about "ver"?
I've included a link that talks about "a" in Spanish.
Hope this helps (and if I'm wrong I hope someone corrects me immediately)!
