Hey guys, I just purchased a refurb mac pro 3.0 Ghz. I installed 8GB of RAM from OWC. Long story short, I installed Handbrake and it keeps crashing on me. I copied "Robot Chicken Star Wars" and have tried to handbrake it about 20 times and it just keeps crashing. Now when "2 pass" isn't checked it takes it about 2 seconds and says its done and the file is only about 4kb. But every time I tell it to 2 passes it crashes. I have tried to re-download it and then downloaded a older version and its still doing it. Any thoughts?
