playback issues on YouTube 2

I keep getting that awful spinning wheel when I try to watch videos, and then it just buffers forever. Sometimes the audio cuts out but the video keeps playing, or it freezes completely and I have to refresh. It's super frustrating when I'm in the middle of something interesting.
