To have the speed functions properly working you need to 'LOAD' a replay, make sure you don't 'QUICK LOAD' it.
Normally loading it will take a bit more time but it shall grant you the use of the speed function.
Pressing the . (>) button will make the replay speed up and pressing the , (<) button will make the replay go slower until it hits the point where it will go backwards.
