The fix proposal was not working correctly, as it was making segments unreliably appear on on-demand content. The fix was therefore reverted.

The problem is related to the DVR window (zero for a livestream) which needs to be taken into account to display only segments within it. This theoretically requires observing timeRange updates (easy), but then reloading the panel (hard to do efficiently, as tvOS info panel does not update during playback). We have a reload mechanism in place, but it seems to be quite slow if done too frequently, and the current position in the info panel is lost.

The best way is probably to open an Apple bug report so that the info panel is properly updated when changes are detected.
