Sadly at this time, the video downloader will not work. In the future we may start supporting the newver VoD system, but it is too much work for what it's worth at the moment. There are a lot of different applications that can download Twitch VoD's available online though.
Thank you for visiting our site, and we are sorry for any inconvience this may have caused you. Please do check back in the future though or follow us on Twitter for updates if we do end up supporting Video Downloading.
