I now have a rendering thing going on also. I went to render a 2;30 project, and it took 2 hours and 3 minutes to render. When I play it back, it shows the first screen, and then locks up the video. I tried doing the same thing in Cinescore in QT, and it does the same thing there. Both programs Vegas & Cinescore are updated to the current version. Never used to do this.
