I believe that I have figured out what has been causing the Green screen problem on my laptop. I am posting this in case it might be of help for someone with a similar problem.

Pinnacle sometimes gives a “not responding” message when performing a task. Initially I would shut down and start over. Then I started using Microsoft's Task Manager and discovered that even when that message came up, if Task Manager showed CPU resources were being used, it was still performing the task. I then started using Task Manager whenever I used Pinnacle so I could always check.

Here is a summary of activity since I last posted.

Problem 1:

Selected 633 scenes from Album to copy to Timeline

Opened Task Manager

Green screen appeared when 'move taskbar' showed about 80%

Problem 2:

5318 scenes in Album - Selected 548 scenes from Album to copy to Timeline

Green screen show immediately

Tried to recreate, but unsuccessful

Problem 3:

1921 scenes in Album

Opened Task Manager

Clicked on scene in Album and Green screen appeared in Preview window

Problem 4:

1-Opened Pinnacle

2-Opened Task Manager

3-Selected AVI file from USB drive to load into Album

4-Immediate Green screen in Preview window

Shut down Pinnacle and Laptop and disconnected USB drive

Repeated steps 1-3 and got Green screen

Shut down Pinnacle and Laptop and disconnected USB drive

Repeated steps 1-3, but did NOT open Task Manager and no Green screen

Shut down Pinnacle and Laptop and disconnected USB drive

Repeated steps 1-3 including Task Manager and got Green screen

I have now stopped using Task Manager since it appears that under some circumstances there are some conflicts with Pinnacle processes.

Since then I have loaded 15 tapes onto the computer. Each was >5 hours and had dropped frames varying from 0 to 324. The 42 movies on these tapes have been edited and burned to DVD disks. I have had no Green screens or any Audio/Video out of sync.
