Hello fellow waste - explorers !

I am planing on starting a Let's Play Fallout New Vegas series, the only problem/ question I have is:

Do I have permission to record and post videos about New Vegas because of the new Youtube Copyright system ?

Because I saw some youtubers complaing about getting copyright problems with new vegas videos.

So what can we use and what can't we use ?

I saw some people turning off their radios because they are afraid of getting copyrighted music - is that true ?

So can I promote this awesome game ?

My channel is brand new and I am hoping to start off with New Vegas: http://www.youtube.com/user/IvanTheTV

P.S. It would be great if you could pin a topic regarding this new copyright system Youtube is using and explain how it affects us the players that record and post videos.
