I just found a beginners video that includes a lot of strumming lessons:

It should last you about a month or two.
Two things about the things the teacher says though that I disagree with:
1. The position of the thumb. If you´re just starting out learning to play you might as well get it right from the beginning: The thumb should NOT "peek" up over the neck. It should be placed on the middle of the back of the neck. This way you´ll never have problems playing clear notes.
2. On tuning the guitar he says that you can tune it by loosening the string. DONT do that. Always tighten the string to get it in tune. If you "overshoot" the tone and make it higher than it should be loosen it below the correct tuning and tighten it up until you reach the right tuning. If you loosen the string to hit the right tuning, the guitar will be out of tune before you have finished tuning the rest of the strings.
Have fun
