I have SL Installed and with this obviously comes Quicktime Player - Version 10. However, I wanted to convert some video footage and noticed to do this I needed QT Pro. So I looked into it, and saw it was £20 and thought, eh, if it works, it will be worth the £20 spent. I have now purchased Quicktime Pro and realised its Version 7. Have I made a mistake. It seems strange that I download a Version 7 to do what I need when I have a newer updated Version 10 installed. I am now totally confused.
