I am running Final Cut Pro 3 on my 17" PB. When it comes to real-time and background rendering it seems like my settings are set wrong or something...cause I have to render every little thing before I watch it. I do get real-time previews when I add an effect, but it plays back very choppy, and when i try to watch it in the timeline it says undrendered. Also, isn't FCP3 suppose to have background rendering so that I can continue working while it's rendering? Please give me any input/suggestions...thanks!
