Yes, you can enter additional servers, and the script will add the flv file to that location after it is converted. You do not need to have ffmpeg on the second server, because it is just used as file storage. The bandwidth is kind of shared on both of them. The bulk of it is used on the server that has the flv file. The original server will still use a small amount though, for loading the images and template files, but that amount is nominal. As for how the script knows which to use, it will automatically store files on the most recent server added to the list. If that server goes down and is unavailable, the file will be stored on the original server instead.
