Good news you made it work.
As mentioned in the Doxygen, it might be possible that your framerate is not fixed, hence FFMPEG doesn't use you num and den values as a constant framerate.

I am attempting to save at 25 frames per second, but the properties on the wmv file states it is 30 fps. What should I be looking at to get this set up right?
