This is how I am gonna get Tubi content...

  * open stream in browser
  * hit F12 to get tools and click Network tab
  * filter for m3u8
  * copy the URL to the clipboard
  * timeout -s 2 90m yt-dlp -o "tubisave.ts" "URL"

The "-s 2" sends SIGINT to the downloader after 90 minutes and the .ts file is the content.
