I've tested it with FRAPS, and WMP plays 30fps videos at 60fps where VLC and MPC play them at 30fps. I would like to be able to play the video at the intended fps, is there a way to turn this off? I also installed the CCCP codec if that is of any relevance.
In most cases, with played back video, or even video game rendering, playback uses something called VSync (Vertical Synchronization) where the video is being rendered or played back as it should but the player is syncing with your monitor's refresh rate (99% of the time which is 60Hz, or 60 refreshes per second). FRAPS may simply be reading the vsync refresh, not necessarily the actual playback speed of the video. Unless the video looks like it is running at double speed, then it is most likely still playing back at 30fps.
