Macbook audio stuttering while streaming from Netflix, Hulu, etc...

Question

As of late my wife's 2008 Black Macbook 2.16ghz C2D has been acting up while streaming video. It first started with kernel panics, but Iocated the problem and relieved the Macbook of it. Now though after a hard drive erase to zero, a re-install of the OS, and an uprgade to the ram it has an audio stutter present when watching Netflix. I've checked practically everything on it. Even opened it up to check the hardware. Can anyone help? I ran this diagnostic from some help here in the forums.Can anyone see anything I'm missing? The help would surely be appreciated. Thanks!

Answer 1

You may have tried these suggestions before, but since I do not know the history here goes:
Looks like you have many plugins in your safari.
Disable all plugins except silverlight and try Netflix.
Try Chrome.
Once you run HULU the flash plugin it eat up hundreds of megabites of ram and then KEEP them for hours. It is a FLASH problem.
If you run Netflix (silverlight) after you run Hulu, you will run out of memory pretty quickly. The solution is to quit (not just close) Safari and then go to netflix.
Look at your activity monitor while you are using Netflix. How is your RAM and CPU usage?
Also Comcast (and the like) sometimes throttles your internet connection. Make sure your internet connection speed is still just as fast as it used to be.
