You can go directly to www.sportsbookreview.com/video/user/ to see a list of users sorted by video uploads or www.sportsbookreview.com/video (very top right of all SBR pages) and click on the "All users" link on the right corner or User Content.

It's no Youtube with your own functional channels but all SBR hosted video content can be found here.

Thanks goes to Ivanator.
