I'm using a Mac to try to capture a stream with Debut. The stream plays very cleanly when I don't capture, but when I do capture, it's a little jerky, with quick freezes ever five or ten seconds. That jerkiness is endurable, but not nice. It's an older (2011) iMac, using OS 10.11.6. Is this a matter of my equipment not being speedy enough? I have to assume that streaming servers don't know I am trying to capture (for my own use entirely), and somehow throw in some crap that makes captures not work.
