The following video tutorials are zipped. They must be downloaded
and unzipped prior to watching them on your computer. This is
done because of the large size of the original files. Even in
the unzipped state, a compression routine was used on them to
make them smaller. Therefore, if you get the sound, but no picture
when you watch the tutorials, there is a codec which you need
to install which will allow Windows Media Player to show you the
video portion of the tutorials. K-Lite "Standard" Codec
can be found here.
After being installed the videos will play.
