Choppy Youtube and flash video
Youtube videos but other flash videos consistently hiccup, a few frames freeze but the audio goes on. It makes watching action, sports or music videos unbearable.
I can rule out the cable provider, the router, the network or the specs of the MacPro with one solid piece of evidence: on my MacPro with the stuttering youtube video, playing the same video in a Parallels Windows XP virtual machine using Firefox 3 or IE is smooth and free of hiccups.
Clearly if an emulated/virtual machine can play smoothly, then the problem MUST be in a configuration within the host Mac Pro!
I've uninstalled flip4mac and Perian. Any other suggestions?
