I'm using Video studio 10, and have had no problems with smooth playback during editing since I upgraded to 2 gig of ram...for wedding type video.
Now I'm in the middle of editing a motorcycle stunt video and am having a real problem with skip during playback when I have anything like a complicated transition, or spit screen, overlays, etc.
I'm running a new HP desktop with an AMD Athelon 3500+ processor, 250gig HD with still about 60gig free. I tried stopping all programs running in the background, defragging regularly, but still no luck.
Can anyone recommend a hardware upgrade that might help? PLEASE!

Thanks.
