Please help a noob!!

I am new to all of this. I am trying to get DailyMotion add on. The one i have freezes. I know there is a newer DEV version but i have no idea where to find it. I think it maybe on a different source than what im using. I may need kodinerds repo. But not sure where or how to get that. I have no idea if any of this is even right. Or if i am totally lost. I just need some guidance from someone whos knows more than me.
