There are more differences besides the addition of some bonus tricks.
2003 version: 1 hour 44 minutes
2013 version: 3 hours 48 minutes
Not everything that was in the 2003 edition of the DVD is found in the 2013 edition, and several sections from the original have vanished. These are the following:
CONTROLS: - Classic Pass; - Hindu Shuffle Pass; - One Handed Top Palm; - Elmsley Count
FORCES: - Riffle Force
The new edition not only has more detailed and elaborate explanations, but also some new material. Here's a list of all the new topics:
ROUTINES: - Slop Shuffle; - Card to Mouth; - Blossom Production
CONTROLS: - Gamblers Cop; - False Overhand Shuffle
FORCES: - Dribble Force; - Spread Cull Force
FLOURISHES: - Swivel Change
