If you do not have a fast internet connection, it is best to first download the movie before you play it. In you browser, right-click and select "save target as" or something equivalent.
Unfortunately, a few of the movies may have choppy segments when played with Quicktime. This seems to be machine dependent. However, they should all be smooth and continuous when using Windows Media Player.
In all of the movies, temperature is displayed using the blue for cold material and red for hot material. In some movies, composition will be displayed as a non blue or red color.
The images are in multiples of timestep (which is dependent upon the Courant time), not actual time. So, keep in mind that time is not necessarily linear throughout a movie's run, although it should be approximately so.
The movies are padded with redundant frames to provide slowness and continuity. This is determined on a case by case basis; therefore, it is not appropriate to compare calculations based on their rate of vigor.
