I got the feeling they bought lots of DVDs for a variety of sources; estate sales, going-out-of-business sales, disposals from other merchants or whatever. There's no reason to think some new/shrinkwrapped items wouldn't be in there.
For example: My mother has an enormous collection of DVDs, some of which she rented from the local DVD rental shop, loved, and then purchased a (new) copy from Amazon "just so she owns a copy" but has never rewatched it or even unwrapped it. As I don't watch DVDs, in the (hopefully long away) event of her passing, I'd be highly inclined to see if I could find someone to just take the entire collection off my hands for a reasonable sum. In theory, some of those DVDs, including "new" shrinkwrapped DVDs could end up as FBA merchandise.
In fact, it's entirely possible that she has a shrinkwrapped, counterfeit DVD right now without even knowing it (due to commingling, who knows where the DVDs she orders, overwhelmingly from Amazon, actually came from?); a timebomb waiting to take out some FBA merchant if it ever finds its way back into Amazon's supply chain (which isn't unlikely).
The more I think about it, the more FBA and commingling seem like utter disasters. It's mixing untrusted merchandise into a "trusted" pool; I can't know if the DVD I buy from Amazon came from Amazon or not.
