In the digital video (DLP) presentation, there is a shot of Anakin's golden robotic hand holding Padme's hand during the wedding sequence. This scene was only shown on the IMAX version but was added to the DVD realese
Actually I did see AoTC at a DLP theater (I was living in Florida and saw it in West Melbourne, the theater had just opened about a month before the release and two of its screens were showing AoTC in DLP). I was aware that the scene would be different for DLP so I was on the lookout for it. I saw the midnight release in DLP (metal hand at the end) and then saw it in a non-DLP theater the next afternoon (no metal hand).
