I'm attaching the system info. As I said, it fails with any WMV so I'm attaching the Windows Movie Maker Sample File. http://www.upfordown...load/view/86196 . It's small, and it has the same problem as all the other WMV files.
A little more info -- I need to export the file as a MPEG-2 for DVD. If I try to use the "Smallest File" option, it works (although it produces a file that is not really suitable for DVD burning). If I choose any other option in the MPEG-2 (Normal Quality, Better Quality, Best Quality) it fails.
Since that seemed to point to WMV to MPG conversion, I tried other formats and it looks like I can export to other formats (like MP4) fine. So my workaround for now is to export to HD MP4.
Obviously, I would prefer to be able to use the product as designed, but at least this will allow me to keep going while we try to resolve this.
