A better video for just understanding why the observer-pair time difference exists can be found at http://www.learner.org/vod/vod_window.html?pid=611 . Unfortunately the page says it is only available to web addresses within the USA and Canada.
When the page link opens, go down to the little square icon following #42, The Lorentz Transformation, and open it. The 1985 video is meant as a teaching aid for college (or high school) physics classes and is 1/2 hour long. It covers the simple applied math as it progresses and is an unusually good visual aid to comprehending foreshortening and time dilation of Special Relativity (SR) as we still understand it now. Without the Lorentz Transformation, Einstein's SR would likely not be established today.
