How do I cast my Roku to my laptop pc? Also since I have an online Roku account, is it possible to watch the other apps on my computer and not just be able to watch the Roku TV channel on my computer?
You can't cast a Roku device to your laptop. You may be able to do it the other way around. Only "The Roku Channel" is available via the website. Most services have a way to use them on a laptop unrelated to Roku.
