There are 2 places you can find the effect you are talking about that have superior methods to the E dvd you have. First, Tarbell Course in Magic, Vol. 1 and second, The Complete Idiot's Guide to Street Magic. You can pick up the Idiot's Guide from half.com for $4 + shipping and there is a ton of stuff in the book (379 pages) for street performing.
EDIT The effect is also written up in Carneycopia by John Carney
