It sounds as if you are looking for a Camcorder not a digital camera.
I suggest you post your question on the Camcorders Forum.

I am a high School baseball/Softball coach. I love to break down swings in slow motion and have been told I need at least 60 FPS. I also need a camera that could serve as a regular camcorder for normal speed recording. Is there a camera/camcorder on the market that can accomplish both of these needs and be able to transfer the video straight to a DVD burner. The industry is mind boggling to the Average Joe.Thanks in advance for your help..
