Many SAT>IP devices expose an M3U url using the satip:X_SATIPM3U tag in their XML device description. This lets you import an M3U playlist from another source or something hosted elsewhere. Enter the URL and Channels will import it. You can add an M3U playlist by directly copying its text into the field. You have two options for adding the M3U playlist content. You need to give the playlist a unique name and specify the stream format.

But you can control this yourself by providing their duration in seconds. By default it creates them with 1 hour durations. It will even create special titles, series IDs, and program IDs based on the time slot so that you can make a Series Pass for them.
