i used paypalA couple more comments... General questions about the Roku, bringing them to this thread is probably a good idea: The Streaming Video / IPTV Discussion Forum
Also, you don't need a CC to activate the Roku. They will take Paypal as well. They don't charge anything through it, just set it up so that if you choose to purchase something through the Roku, it will go through that account. Paypal is a little better as then you don't have one other company to update when your CC expires.
