There's a big difference between making things happen faster to keep it entertaining and completely making up nonsense to solve the case. I can't stand the other CSI shows but I like to assume the tests they run etc do actually exist and work, more or less, the way they say they do. I probably shouldn't.
But in this, they had a remote accessed nanny cam projecting the voices, in separate languages, of people in an online auction. Somehow, I'm thinking that wouldn't happen.
