I sat for about 3 hours to try and fix this issue. I used to be able to use this feature to stream movies or shows from my PC to my TV with broken HDMI box and now it doesn't work for videos anymore. I tried every solution on the internet and nothing works. I can still use cast to device to feature photos on it. I tried using my phone Smart View feature and got the same result. Pictures work, videos don't. I think I should mention I don't have Wi-Fi on my PC, so I'm connected with ethernet. Anyone got any idea on how I can get it to work again?
