MovieTexture Issue

Recently Today I have tried creating a movie texture and yes I do have unity pro. There seems to be an issue when I create it and play it using a label, it plays video fine, only problem is there is no sound. So I search and others say to have it as an audioclip, it now plays sound but theres another issue with that too. It plays the video and sound at ridiculous speed, 30 second video into a 5 second video.

Heres my code

 void StartMovie(int WindowID)
     {
         duration += Time.deltaTime/2;
         GUI.Label(new Rect(0,0,MovieWindow.width,MovieWindow.height),TempMovie);
         TempMovie.Play();
         TempStart.clip = TempClip;
         //TempStart.Play();
         GUI.Label(new Rect(Screen.width/2-30,Screen.height-50,60,50),duration+"/"+TempMovie.duration.ToString());
     }

I don't see what I'm doing wrong with this so if anyone can help that would be great. , Thankyou.
