The only problem I ran into was that there was no download link/button. Despite what their directions said, I currently have no way to download my old video because there's no link!
python youtube-dl -t google-video-url

youtube-dl -UUPDATE: Finally figured out a way to download the video, incase you don't see the download link. Find the "cid" from the "Edit Video Info>>" link and paste it in this url http://www.google.com/video/upload/DownloadVideo?cid=[video_...
one uploaded in 2008 has a link but not the one from 2006
