I know that controlling a video's privacy setting (public, private, unlisted) is done through setting the yt:private or yt:accessControl tags. However with a YouTube video, when it is set to private the access to the video can be allowed through a list of email addresses or YouTube usernames.
Is there a way to set this allowed list through the API?
If there is someone who knows of a solution using the Zend Gdata libraries this would be welcomed as this is the library I am using to interact with the YouTube API.
