Only external Chromecast devices are officially supported. While it may work, our player is not developed to support this and we cannot troubleshoot any issues that may arise. Note: At this time, we do not support Chromecast devices that some TVs have built-in. If you have a Chromecast device, you can use that in conjunction with the Google Chrome desktop browser to watch content on your TV.
How do I watch via Chromecast on my desktop?
