download the rpm and double click on it. (or run rpm -ihv something.rpm from the commandline)

or if it for some reason doesn't work with your version of redhat:
http://avifile.sourceforge.net/

The avifile project is pretty much dead though, last update was in 2006 (NeHes tutorials are ancient aswell) and pretty much everyone would use gstreamer these days. (It is far better and works with both free and commercial codecs)
