Hi Charles, sorry to hear you’re still having issues
Playback works consistently across all modern browsers for us, and we’ve had no similar complaints. We use Video.js as the player, if you think you would do better with another we have a feature (undocumented) that will let you grab the video url (.m3u8) via API and play it back with a player of your choice.
Regarding your other issues, you’ll have to describe them individually.
As the streaming system is very stable and feedback is really good, I’m speculating you may be running your tests against an unstable connection or a particularity of your hosting or wordpress setup is badly interfering with ours.
Let me know a good time we can send out a test broadcast (from us) against one of your channels (and which), this way we’d know if you’re experiencing broadcast issues or playback issues, or both, or else.
