Brian, Don't use. Only seen ads on TV and went to the Web Site. It does show Netlix along with:
"Watch thousands of TV shows and movies on your TV. See everything you can enjoy with Chromecast. Go big when you go home. Enjoy YouTube on the best screen in the house. Watch your favorite HBO® original series and hit movies directly on your TV. Instantly watch hit TV shows using your Hulu Plus subscription. Listen to free, personalized radio from Pandora on the best speakers in your home. Watch handpicked Hollywood movies, TV series and originals. Whenever, wherever. Send movies, TV shows, and music from Google Play to your TV."
And with most offerings there is usually a catch or two.
Chromecast requirements?
"The Google Cast extension is available on all platforms, including Chrome OS, Windows, Mac OS X, and Linux. There are no specific hardware requirements in order to install or use the Google Cast extension. However, casting video from a tab of your Chrome Browser has specific requirements depending on your chosen quality settings. Systems that do not meet these minimum requirements will be limited to projecting web pages, images and slideshows, and will not work well for video content. A strong Wi-Fi connection both on Chromecast and your computer is also required for good performance. "
Don't know if Googlecast and Chromecast is different.
