The first channel he wanted to try was RTS 1 from Serbia, known for its high-quality programming, including news, dramas, and entertainment shows. Marko found the channel's live stream URL from an online forum dedicated to ex-Yugoslavian TV channels. He opened VLC Player, clicked on "Media" > "Open Network Stream...", and pasted the URL. With a click of "Play," the channel's live feed appeared on his laptop screen.
