Well now... i am back...
I just received my macbook pro (one in sig) back from apple care and it is stuttering too.. It wasn't before i gave it to them. I have done a complete reinstall. Uninstalled flash and reinstalled it. Nothing helps. It can be 480 or 1080 p it still stutters... youtube or hulu. While playing the video cpu is at 50%. On descrete graphics. It didn't do this before i sent it to them... all they replaced was the screen. Suggestions?
I didn't edit because it wouldn't put the post up to the top
