It has been mostly working for me, but I've noticed issues with CB lately with some streams not really working, even on their site. I can take a closer look if this isn't the case, but for streams not showing correctly in the app, open it on CB and see if it works. typically the CB player will try to load them for a while, then give up and switch to a fake 'video' using the stream preview images. You'll notice this is happening if the video controls don't show up.
