The show is focusing, at least in part, on the legacy of Kurt Cobain. Click for more details and photos. This show will still be repeated on the CMT network in Canada on April 15, 2003 at 9:30pm and April 16, 2003 at 12:30am. There is also a CMT network in the U.S., but I don't think they show Impact. You can also download an AVI of Tori's appearance on Impact at Tori's Beauty And A Gun.

Many thanks to Ian for telling me all about this program. He also sent me screen shots that you can see below.
Tori appeared in at least two segments on a show called "Impact" on the CMT Network in Canada. The title of the episode was "Surfin' USA". It was an episode regarding Kurt Cobain and Tori spoke about him and the music. The show was broadcast for the first time on Friday, April 4, 2003 and repeated several times after that. Theyt even played a little of Tori's cover of the song. Tori talked about the impact of the song and had many interesting things to say about it. She talked about how she was trying to get at the meaning of the song through a different way.
