Behind the Scenes Video of her on Stargate Atlantis
I found a video of Dawn on the MGM Stargate website. It's a behind the scenes look at the episode she was in. Shows some clips from the show, and also shows her talking about the episode.

It's only a couple minutes long, so it doesn't take forever to load or anything...
