I've had this problem before, and I can't remember the solution. I am trying to export my edited timeline as an MPEG-2 so I can put it into DVD Studio Pro to burn a disc. When I go to do so, it tells me the timeline needs rendered, even though I have selected render many tmes, in all configurations (render all, render both, render needs rendered, etc...). When I click to render, the render window flashes on the screen for like a half second, but it never renders. Does anyone know what's wrong? Is it a scratch disk or RAM issue? I have had success exporting as quicktime, but don't I sacrifice quality when I do that? Any help would be GREATLY appreciated. Thanks!
