I have Vegas Movie Studio Platinum 6.0 and when rendering a 30 minute (456mb) movie it freezes at 35% complete when choosing DVD (NTSC and MPEG1 and MPEG2) on Make a movie option and 55% when choosing VCD. My system has a Pentium 4 1.6 GHz with 756 Mb Ram which meet the minimum requirement). I also am rendering to another drive that has 90GB available.
I have rendered movies before in Vegas Movie Studio 4.0 that were about the same length and had no problems. I did use more moving backgrounds this time with picture video overlays so maybe that has something to do with the problem.
Any suggestions on how to get this video rendered so I can burn a DVD using DVD Architect.
