On a laptop running Windows 10 with the latest updates.
VLC is working fine, although it has had some issues discovering my Chromecast, but eventually I can find it.
However, the problem is that when I set "renderer" to Chromecast it just shows the title on the TV, with a black screen and a grey bar.
I can cast to it using Google Chrome or apps on my phone.
The content I'm trying to watch is IPTV being streamed through a playlist file (I believe MPEG-TS)
VLC does give me a message about encoding and CPU usage just before however
