I don't have information about a dvd for coaching young kids, but I do know that if you show them the love of the game and keep it fun they will have fun while they learn to play. Remember keep it simple, keep it fun. You will be laying the ground work for them.

Weplay.com is your dvd. There are some great drill videos on the site. Save your money Keep It Simple. Fundamentals are the key. Stay one page ahead of your kids and you will be fine.

Here's a couple more sites to pull ideas from:

Like stated above, if it's fun they'll learn. Some key points are:
-No laps, no lines and no lectures.
-Practice time is about the same as a match.
-Avoid drills and focus on fun games that challenge thinking and use of basic skills.
-Use progressions to build a skill or concept.
-Maintain discipline and attention by keeping them too busy to get into mischief.
-Avoid standing around and watching others by setting up smaller activities that maximize time on the ball. Check out any info on the use of small-sided games like http://www.oregonyouthsoccer.org/test/coach/small_sided.pdf
