Youtube blocking my Halo 4 videos - need advice, please help!

People seem to be uploading them now, which makes me wonder if it is just a timed NDA thing maybe?

Realising how lucky i am here o-o But thankfully i haven't uploaded any big brand games onto my channel, just indie games, i find indie game devs to be more chill and less caring about you uploading their content. Though i have gotten a content ownership notice, but thats for some music i used from a artist who i got permission from, he eventually just took off the marks, placed an ad and put his itunes into the side of the video, which im cool with. But yeah, try to avoid big brand games because they often do get people into trouble. As for a NDA i did hear about that but i thought it was only till release for people who got the game early? Anyway, hopefully you guys get everything fixed up and keep making some cool videos c:
