So after doing the things that were suggested to me in the last thread which included updating my flash and safari and trying different browsers I'm still experiencing problems with my new MBP playing HD flash content from Netflix, Youtube and pretty much everywhere else. I'm wondering if maybe the next step is to setup an appointment. I took two videos that kind of show part of the problem which is the video will either lag behind the audio or they will stutter every 10-20 seconds which is clearly visible from the videos. I'm also using the same network as my other 2 computers which have no problems so I'm assuming it isn't the internet connection. http://www.youtube.com/watch?v=feDjVdEYSNw http://www.youtube.com/watch?v=iSDWA_CSvpY I even experience lag when typing text right now. Is this normal or is there something seriously wrong with my computer?
