Gaigo TV is certainly one of the most unusual English-teaching initiatives on the web.
In the event you wish to use this in class you should be able to download it with downlaod helper and play it with VLC media player. Normally copyright issues would apply but D.L. Wilson - the founder and creator of Gaigo TV - posted a message here saying: "We encourage teachers to make a copy and use in the classroom if they like."
Teachers may consider using the clip along with the Japan Times article mentioned below.
As of February 2010 the first video lesson of Gaigo.TV was available, free, online.
