I have antivirus running in the background but shut everything else down before I start editing. I think one of my biggest problems is that the still .jpeg pictures I am using are too large. I am convering them to png and resizing. I am using a USB 2.0 drive and will move all the video files back to that.
I upgraded to 3gig of ram when I first started having problems and it usually only eats up 1.5 gig or so. With the new version (d) build 139 I had a major problem with some HP office jet codec conflicting with the upgrade. It kept wanting to install Photogallery. What a pain that was. I’ll keep tweaking the system as suggested and see how that works out.
Thanks for you help.
