Improve video playback performance
I have a 2006 mbp that in the last year or two exhibits sluggish and choppy streaming video playback (Netflix, YouTube, etc ) but doesn't seem to when playing local video files. Other devices on the wifi network do not experience this, so it's not the ISP or network. Was wondering what could be at issue & what ways to improve video performance?
Thank you.
