Home Sharing Issues

Hey there!
I can view files on my tv that are in folders that are on my homegroup, when i want to add a new directory eg a folder called "Movies" i go to the "share with" drop down and select "homegroup" once i do this and go to find the folder, it isnt there, almost as if its never been added? any ideas?
cheers

Doesnt matter, got it working, just had to add the documents directory, silly me cheers
