Repositories
During installation you can select additional repositories (apart from Core, be it CD/DVD or FTP/HTTP). You have Extras configured but can add any repo you wish. Take into account that adding repos can make installation longer, specially if you do it over an ADSL line (like I do, and a slower spanish ADSL, thats a 1mb/300kb line).
