MovieTexture.duration is giving me the wrong time.

I am streaming a movie (.ogv) from the StreamingAssets folder in Unity and when I get the duration (after I play the texture), it gives me a really wonky number like 701 seconds instead of the 45 seconds that is the correct runtime of the movie.

Is this just a metadata issue that I have to figure out how to change that? or does that data not get loaded in first when you're streaming and I'm getting some random junk number? Please help!
