Q: Quick Time Player on Mavericks won't open MPEG-4

Despite advertising otherwise, Qucik Time Player (10.3) in Mavericks won't open MPEG-4 movie files. Why is this when apple clearly state that it does in this article (above).

 

Why is this ? .mp4 file downloaded from the internet (youtube).

 

Thanks
