i tried to change it to all kinds of formats but it still doesnt work. The only thing i did to change it was change the name to "name.mp4". am i doing it wrong?

Changing the extention name will not help. You either need to use a Video od Media converter or else download and use VLC Player (free) which plays many video formats that Quicktime cannot.
