Cristian Baldini contributed to the iptv-org/iptv repository by enhancing the AR channel lineup within the ar.m3u playlist. He added a new AlternaTV (720p) stream and updated the channel’s display name to improve user discoverability and experience. Addressing playlist accuracy, Cristian fixed a bug involving swapped URLs between AlternaTV.ar and AiredeSantaFe.ar, ensuring each stream entry pointed to the correct source. His work demonstrated careful playlist management and attention to detail in m3u file editing, with changes applied consistently across multiple commits. This effort improved the reliability and usability of the playlist for end users seeking Argentine IPTV channels.
