Canon T2i w/ Extreme Pro UHS1

I have recently bought a SanDisk Extreme Pro® SDHC™ UHS-I Memory Card - 16GB for my Canon T2i. Taking pictures is fine but whenever I record a video (1080p) and view it later on my PC, the video is messed up as if it is playing at low FPS. The audio is not effected. Looking through the LCD it is playing normally, only when I insert the card on the PC I am able to see that there is something wrong. 

I do not understand what is wrong with the memory card as it is not my camera and my older SanDisk Extreme SDHC Class 10 - 8GB does not do this.
