I'm having a lot of problems captuing footage I shot 24P Advance. I'm using FCP 4 and I have a Mac G5 OS 10.3.9, 768 MB memory and I'm using an Iomega 250 GB external HD as the scratch disk. FCP will periodically quit when I'm trying to capture footage and I need to restart the computer. What could be wrong? Do I need more memory?
