To insert a stream or podcast into the playlist, in the menu click Playlist -> Add URL...
A window will open where you can enter the stream URL and set the duration:
Check the Podcast checkbox if a URL points to a podcast: in this case, RadioBOSS will select the newest stream from the feed and play it. When the podcast checkbox is checked, the URL has to point to an XML podcast feed.
When the Stream duration is set to 0 (zero), RadioBOSS will play a stream until its end (or until something else is started in the playlist). If the duration is non-zero, RadioBOSS will play a stream for a specified amount of time, restarting the stream in case of any errors, e.g. connection failure. Note! Streams with no duration specified (0) will not be restarted in case of an error.
