Insufficient permissions for title on video

[phlegx]

I instantiate the object like this:

@client_video = Vimeo::Advanced::Video.new( APP_CONFIG['vimeo']['client_id'],
                                            APP_CONFIG['vimeo']['client_secret'],
                                            :token => "USER_TOKEN",
                                            :secret => "USER_SECRET"
                                           )

Then I get the video ID by executing

@client_video.get_all('USERNAME)

and then I try to add/ change the title of that video

@client_video.set_title("VIDEO_ID", "Title change")

But I get the following error:

Vimeo::Advanced::RequestFailed: 99: Insufficient permissions, explanation: The user does not have permission to do that. Method requires write privileges; read granted.

The application and oath tokens I use are correct since I tested them with the "Vimeo::Advanced::Test"

Any ideas what might be wrong or what I'm doing wrong here?
