Hey all, I'm getting pretty annoyed at the inability of my macbook to play youtube videos all of a sudden. I first noticed it about 2 weeks ago. I tried updating Flash (3 times), didn't work. I tried the html5 trick, still doesn't work (audio is fine, video super choppy). I'm pretty fed up! I've never had such problems on my mac in 4 years. Why now? FWIW I'm using Leopard.
