Q: why won't QuickTime Player open any video file?

I've downloaded the new Mavericks and am up to date on QuickTime as well but this will not open any .mp4 file. Every file I try to open I'm redirected to apple which shows me all the files that QuickTIme will play which are exsactly what I am trying to open.

MacBook Pro, OS X Mavericks (10.9.1)
