I don't see the file....are you sure you uploaded it?

BTW, most likely this means the input content is NOT telecined, but
just plain 60 field/sec interlaced. It's also possible that you
captured at the wrong framerate (i.e. anything but 29.97 is wrong).
But I'd like to look at the file anyway to make sure, so let me know
where you put it...
