when I change the speed of the video

[Dr_J_Mack]

in my video i have several clips.  the video overall is 2 hours.  I need to change the speed of each clip.  when I click on the clip and change the range speed to 200%, video play back is frozen on the first clip.  what is wrong.

can someone walk me through this?

I've watch multiple tutorials and can't figure this.
