I am very disappointed by this Pinnacle 18 plus. The 16 Plus Pinnacle worked fine but by upgrading my computer can not re-download the update Pinnacle 16 Pinnacle 16 Plus I bought there is one. So I decided to buy 18 Pinnacle Plus CD release. What problems. Could not complete the rendering to burn a DVD. Finally, I could import my editing work on 18 more in the Pinnacle 16 and burn my DVD's that way! For a week I expect assistance from after-sales service and nothing. However, it's been years that I use Pinnacle
