Hi what is the difference between Pinnacle Studio Ultimate Collection 14 HD, and Sony Vegas Movie Studio HD? At the moment I am using Cyberlink Power Director which is OK, but makes the pictures blotchy and over sharp when I replay back through a DVD player. I notice it occasionally crashes, and also makes a horrible ‘white noise’ sound while I am editing it so I have to stop and give it a few minutes. Which is the better programme? Pinnacle Studio Ultimate Collection 14 HD, or Sony Vegas Movie Studio HD? Any advice would be most helpful. Many thanks.
