You will need to create a Facebook Application for your website at http://facebook.com/developers. This provides an Application ID which is required by the Block to interface with Facebook.
Most of the settings in the Application setup are not required, however you will need to give your application a name (generally the same as your website) and provide the details of where your site is located (the Site URL).
You will also need your Numeric Facebook ID which you can find at http://findmyfacebookid.com/, you can also find your Facbook id by visiting http://graph.facebook.com/”your account”
*Only works with Facebook Fan Pages, Does Not Display public videos from Personal Profiles.
The main differences between pages and profiles:
When adding the block to a page, you will need to provide your App ID, App Secret and Numeric Facebook ID.
Setting the number of videos per page will change the number of videos displayed before the pagination displays, setting this number higher than the number of videos in your album will hide the pagination.
Setting 'Show Titles' to No, will hide the video title.
Leaving the 'Truncate Titles' filed blank will display the full title.
Setting 'Show Video Length' to No will hide the video length.
