As I recently "discovered" tools to view windows media files (^_^;
I have gone over to www.animate.tv to check out what kind of
seiyuu related files they have over there..
There are "web radio/TV" shows, "news clips", promotion clips, etc.

In the news section I found two Cutie Pai interview movies
and one Chori Wonton (Miyanishi Noa/Sakurai Sara) movie.
(I already had the Chori Wonton movie.)

I've also found Kouda Mariko, Iizuka Mayumi, Kingetsu Mami, and
some others.  I'm gonna try to make a list of what is available.
The quality of the "broadband" version of the movies files
isn't that bad.
