While each feature and source has its own settings. There are a few settings that covers the more generic sections, or features that are used by most media sources. All of these and other settings are saved in json files which can be found in the settings folder in your open tuner folder.

You can access the Main settings from the Main menu and then selecting Settings…

Media Source

In this block you can select the source that should show automatically when its started up. If you use one source more than the others then thats the one you typically want to select.
Media Settings

In Media Settings you can modify the following:
Media Snapshot Path: This is the path where snapshots and video recordings are saved. This can be any valid writable path.
Media Players: You can specify the player used for each tuner. If your source has 1 tuner then it will use the first selection. If your source has 4 tuners then it will use each specified media player.
UDP Streaming Settings

When connected to a source your can start the UDP streaming. The port and the IP can be configured for each tuner. As with the media players it will use dependent on how many tuners you have. For example. If you use the Minitiouner with dual TS then it will use the first two settings for its two UDP streams.
