I just got a chromecast and I'm not sure if i had the wrong impression of it or what. I understand it streams video from netflix and youtube and that's all great, but I mostly watch movies that I have downloaded on my tablet. I was hoping to stream those movies from my tablet through chromecast. Apparently that's not what it does. On my tablet I use MX Player and I've read that doesn't stream to chromecast. Are there any free video player apps that anyone would recommend?
