I'm currently running media studio pro 6 on a Athlon 1600XP. When I use the editor to edit a mpg2 file that is about an hour and a half long the program will start fine for a few minutes. Then everytime I touch a control the program will freeze for about 30 seconds with a lot of disk activity. After that the program will seem to work again but then it will freeze again for 30 seconds. Anyone with any advice?
