Just being anal: Apple's Blades of Glory trailer is different from both the IGN and official site version:

In the scene in the middle of the trailer, Will Farrell's character says "Matching junk" in the IGN and official site version, while in Apple's version he says "Matching sets of crotch luggage". The date card at the end is also different ("Coming soon" vs "March 30").

Not sure if a different source has anything to do with a bad encode.
