HLS Backup Stream Loading Prior to Primary Stream:
I have a question about the HLS backups streams and how Roku handles the playback of the primary and backup streams. With our configuration we are seeing Roku loading the backup stream first and then pretty quickly adapting and in the process switching to the primary stream. But our backup stream is not in sync with the primary stream so the switch between primary and backup is pretty disorientating.
Couple of questions:
1. Why does Roku load and playback the backup stream at all, as opposed to working with the primary streams unless it encounters a problem?
2. Is it uncommon or common to have the primary and backup streams out of sync (as we do in our configuration)?
Thank you,

Someone at Roku will need to confirm, but I don't think the Roku supports backup streams. In my (limited) experience with those playlists that have backup streams (two or more streams with the same bitrate), the Roku tends to either pick one randomly, or uses the first in the list. I'm not sure which, but it seemed like the former, as you'd expect it to stick with the first for every bitrate otherwise.
