Lost on iTunes: a cautionary tale

So my wife and I are halfway through season 3 of Lost. We're moving forward a few episodes at a time, mostly via iTunes (via our Apple TV).

So tonight, we finish episode 12 ("Par Avion") and download episode 13 ("The Man From Tallahassee"). The "previously on Lost" recap begins, and suddenly we start seeing a ton of stuff that hasn't happened yet. After much investigation, we conclude that iTunes is actually serving up episode 16 ("One of Us") when episode 13 is requested.

This is the first time I've experienced a problem like this with iTunes. We spoke with tech support, who was helpful and offered us a refund. They will be changing the file on the server shortly.

But it begs the question: how many people have watched Lost on iTunes and didn't realize what happened?

Anyway, just putting this out there for the record. Perhaps I'll start a Facebook group for people who've watched Lost season 3 on iTunes and have been traumatized by the sudden fast-forward of plot.
