Live tv channels can be directly accessed by clicking on the channel numbers or Guide button on the remote. It also has Guide section on the top row. In the "Home" section, by scrolling down, we get to see our top channels (most viewed channels). Around 20 channels can be seen in that row.
Not sure about the satellite channels but many internet channels that are available on the app aren't available in the binge plus set-up box (2000 series). Vice versa, selected few channels are available only on the setup box and not on the application. Though almost all the main GEC channels are available on both the platforms.
