We are officially releasing an app for Roku (in beta). See the blogpost for all the details, plus installation instructions.
Feel free to comment here for your experiences with the app.
EDIT: Can't hear sound? From the blog post:
...to hear audio, you need a TV, AV receiver, or soundbar that can decode Dolby Digital or AC3 audio over HDMI. Most modern TVs can do this, though we’ve noticed a few Samsung TVs cannot. All Roku televisions should be able to play audio without any trouble.
