New to the xbox 360 need a couple of question answered?

[TyL3R AdAmZ]

On my avater I bought a WWE Title belt that he holds but it doesn't show him holding it on Socal screen but im wondering if anybody else sees it?

How do I add music or Videos through USB I know ps3 can but 360 doesn't seem to work?

What are partys? is it like a chatroom like on ps3. I was watching netflix and I invited my friend whos also watching netflix but I couldnt chat with him or anything

I will answer your questions individually.
1.) Try re-putting the the belt on your Avatar. You may not have saved it appropriately. Also, try hovering over your Avatar when your on your social area.

2.) You add music by putting CD's into the drive and downloading them directly to your Xbox. The only way I know of to add videos is if you purchase them off the Xbox Live Market Place.

3.) Party's are where you can socialize with people in private, or with a group of people in private.

4.) When you invited him, it only made it so you two can watch the same movie together, not socialize I do believe. You can invite him into a party to fix that.

I hope I helped you. Best of luck.
