Apple and the Postal Service: Same director

Since the debut of Apple's Intel ad at Macworld, people have noticed the resemblance it bears to a certain music video by the band The Postal Service. MacTV has a nice side by side video of the ad and the music video. They also note that both the commercial and music video were made by the same directors, Josh Melnick and Xander Charity. I agree with Leander at The Cult of Mac Blog when he says that the legal implications here are quite unclear. Are these images the property of the directors, the ad agency, the band, Apple? I'm not familiar with this type of thing, so if you've got a legal background, pipe up.
