My big gripe is that X videos don't seem to support Chromecast at all. I used to watch SpaceX launches on my TV :(
Just watch the everyday astronauts coverage on YouTube! Great commentary, and feed from the official space x stream as well as their own cameras
Space.com's YouTube channel always has a mirror of the official SpaceX livestream:
https://www.youtube.com/@VideoFromSpace/streams
Or if you would like additional commentary and extra camera views, there are independent channels such as Everyday Astronaut, NASASpaceFlight, Spaceflight Now, etc.
I now use AirPlay to extend a MacBook screen to my TV and play the stream that way. But it's so needlessly complicated compared to before :/
> X videos
cough cough
There is an Android TV App apparently: https://play.google.com/store/apps/details?id=com.x.xtv
Load it in Chrome and cast the tab. Sucks that you have to involve your computer for the duration, but that's the most reliable way to do it IMO.
