The reason that you are not finding much information on this is because this is not a supported method of streaming. I have seen, on rare occasion, this work, but I am not sure how. I would reach out to Google Chrome support and see if maybe they have a work around or method that may work for you if you want to be able to stream like this.
I hope there is a legal or contractual reason for this, because if it is Sling's decision, it might be the stupidest thing I have seen. And I have seen someone try to circumcise their self...
But seriously, this is offensive, because I paid for all your equipment and apps, and while I love the product, I cannot use my laptop to throw the signal to my TV??? This mentality is the opposite of why you guys actually had success, and were able to be bought out.
I have seen multiple posts about devices and Chromecast. I have searched and been unable to find any posts in regards to web based watching and able to use with chromecast. I usually watching my Slingbox via slingbox.com and can watch great in Chrome, Safari, etc. I am curious why I am unable to "Cast" the website to my screen? I went through the comparables and believe everything I read was only for mobile devices.
Any help would be great. I have a Imac and MacBook Pro. Looking to simply cast from webpage to Chromecast.
