Either in game or on forza? Where
By get, assume you mean download? forzamotorsport.net/.../Profile.aspx
yes download. I looked in that link I dont see anywhere to get a movie. I have uploaded one.
Strange that there's nothing under File Depot.
Go to your Media Gallery, on the far right there should be a grey box titled "Large Media Files". It should have your most recent movie upload (You can only have one up on the site at a time), and click the download link.
