Why can't my pictures render in iMovie? When I apply a Ken Burns effect to them, they just sit there in the timeline and never render. I recently had to have my iMac G5's Logic Board completely replaced because it was shot (the computer was barely 4 months old, so you can see how I might be getting tired of Mac problems). Prior to the Logic Board going to hell, I never had any problems rendering images in iMovie. I've tried all the fixes recommended to other posters here who've had the same problem (repairing disk permissions, emptying iMovie's trash, saving, quiting, restarting, etc.) but nothing works. Honestly, I am really getting sick of encountering so many problems with my, as advertised, "carefree," "easy to use" iMac. It seems I spend more time searching for answers and troubleshooting than I actually do using the computer. Can somebody PLEASE help me before I take a hammer to this thing?
