I remember it being 12 minutes long whereas the theatrical release was 7-8 minutes. There was at least three added scenes:
Dawn Before the Podrace—Anakin gets up early to prepare the pod for the race and has a brief chat with Padmé.
Complete Podrace Grid Sequence—This scene shows more of the participating racers and creatures in the crowd, later added on DVD.
Extended Podrace Lap Two—This lap shows some more of Sebulba's "creative interpretation of the rules" and further proof of just how special Anakin is, later added on DVD.
