How did you poeple obtain the code to put youtube on the Roku box? How do you get codes to put other sites on Roku? I just got it today, was a sinch to set up--gets a great signal--for my router is on the 2nd floor of my house!
The code mentioned is no longer valid, RateRix has issues, but as mentioned in a post above, check out the PlayOn option. You can add the channel to your Roku, and the free/lite version will allow you to watch YouTube videos, it's been a great option until Roku adds an official YouTube channel.
