You fail it.
Your video doesn't show any fakery, it just offers equally pretentious guesses as to what happened on a particular piece of film. More to the point, both of these guys have an IQ of about room temperature. They're plumbers, not rocket scientists, and probably think the iPod is "pretty neat". You're giving them a lot of credit when you allege they're "shuffling sound files". The recap episode is particularly revealing. After wasting eight hours of network time, they got ONE - ONE SINGLE evp the entire time.
Either the skinny guy is a total fuckup and can't select the single EVP in the EVPs folder on his iPod or it's legit.
Explanation B, which I'm a lot more comfortable with, is that this stuff is really happening but they're misinterpreting it because they're primed to believe in ghosts. The lighthouse episode with the thing running up and down the stairs is a good example of this. They might think they're seeing a ghost, but in a lighthouse, you're going to have birds, and they don't need to start at the bottom of the stairs....
