Question: Quicktime video stuttering
I assumed this was a more widespread problem but maybe I'm misnaming it. I believe my new computer should be more than capable of playing back recorded video in Quicktime, but while the audio plays seamlessly, the video stops and stutters, sometimes catching up with the audio, sometimes not. What am I doing wrong? Do I need a better video card? I don't notice any performance limitations on anything else I'm running. Thanks so much for your suggestions!
