I downloaded about 3 different movies and when I play them they are upside down. Is this due to the way the movie was saved or do I need special software to rotate the movie 180 degrees? Your help is much appreciated.

Might be a codecs issue....
You could try to use a different media player such as the free VLC player with built-in codecs which can play almost all media files without problems. You can downlaod it from here:

As a side note, to preview files with it you'll have to open the files directly from the Incomplete folder and not via the preview function.
