I have not used them for hosting, but I can tell you that if your site is using a lot of bandwidth, first I would look into getting a host (or server) that does not meter my bandwidth. Second, I would look into ways to better manage the bandwidth. One of the things that I am doing on my site is connection throttling for the playing of the movies. My movies download at a set speed to the person's computer. This way, if they do not watch the full video, the full video is never downloaded to their computer. I'm also doing seeking so that if a person jumps between points in the video, the system stops downloading from where it is at and starts downloading from the new point, thus saving bandwidth.
