Surprisingly, Balance of the Force has been up there for like 2 years and the first few parts of Clone War have been as well.
Sony & LFL raise copyright objections to youtube every time I upload a part, but they allow the videos to remain up.
I just receive this message a message that my video contains content owned by Sony & LFL each time and then told that no action is required on my part but that ads by LFL and Sony may appear next to the video.
In essence, they don't care because they're using my edits as a free billboard which is fine by me.
