For a long time I've experienced certain videos have extreme lag on youtube, like video dropping behind audio within seconds then just skips content to catch up, then repeats. Most youtube videos are fine, but certain channels like anything from "daily dose of internet" will always do this. I can't see anything different in the logs. Does anyone else experience this? 
Forgot to mention, I'm on 9.2.8
Might be answering my own question here, but seems something to do with the MPEG-DASH (what ever that is) setting in the youtube app. When I disable it works, wonder why it only effected certain videos though.
