You need a VPN, of course.
I can't vouch for any of the VPN services, marky. But Relakks ( hXXp://www.relakks.com/ ) is cheap at just € 45,00 for 12 months. Relakks is located in Sweden, so it will not give you access to Hulu videos (should you happen to be outside the USA). But it will do a fine job of hiding your IP address and encrypting your torrent traffic.
Another one to look at is Happy VPN ( hXXp://www.happy-vpn.com/ ). Happy VPN is unique in that it can be configured to give you access to both USA-only video sites (like Hulu) and UK-only sites (like the BBC).
