I’m not aware of an alternative TV App for android tv. On my android TV live tv is also wrapped within the android interface but other sources like HDMI inputs are not.

If you can switch to HDMI sources outside the android apps then maybe the best thing to do is get a separate basic satellite tuner device?

It seems shitty that google are effectively hiding your inbuilt tv tuner behind an app with all their advertising and other crap.

Genuinely not had a problem with mods, and I’ve been PC gaming for decades. Of course sometimes mods don’t work but thats life. Just be patient, you’ll get it done.

Decent mods have a readme file - follow the steps strictly - no skipping thinking you know better - and they should work.

Also look on YouTube or search online for guides - people often provide step by step guides to mod games purely out of a love for gaming.

Keep going - mods can be great, and its one of the many benefits of PC gaming. You’ll get there!
