Download Quicktime Player For Mac Os X 10.5.8

"I have a Mac OS X 10.5.8. I downloaded some mp4 videos and quicktime but cannot get them to play. When I open quicktime, open file, mp4, there is a picture of the video with no sound and its not playing. What am I doing wrong? Where should I open the video to play it? itunes or imovie?"
