I digress, and to be honest, the whole SOPA thing is freaking me out big time and didn't know how else to react. I don't want to get fined and/or go to jail for uploading walkthroughs on youtube.
You probably won't.
This is meant to target major piracy, I doubt they'll spend their time going after small fry pirates and people who have minor cases of copyright infringement. I seriously doubt, say, Nintendo would get on your case if you did a walkthrough of Skyward Sword. It's basically free advertising for them.
