Downloaded lots of builds from there and all gave the same error.
got a version from here http://ffmpeg.zeranoe.com/builds/win32/static/ffmpeg-20120519-git-31dfe20-win32-static.7z which did not give the same error but it does not understand the command for splitting the clip in 10 minute chunks.
would be great if the guy that made this program told us exactly what build off FFMpeg he used.
