Is it possible to cast ?

Ok, not sure if mezzmo can help with this.. i use it for streaming from my PC to TV using PS4 or my tvs DLNA and it works just fine.

But what i want to do now is be able to stream videos i watch on the internet to my TV also, say like Discovery.com and be able to play it to my TV using my PS4 / Firestick or DLNA server. Is this possible?

Its giving me a headache trying to figure it out. Thanks.

Hi,
you can try adding the URL for the video to Mezzmo http://www.mezzmo.com/wiki/doku.php?id=adding_urls&s[]=url to see if the video is detected. Mezzmo supports a range of websites so it may be possible to add videos from Discovery.com to your library and stream them to the devices in your home.
