Hello all. Windows 7. 32 bit. I have Cyberlink Powerdirector 8. If I introduce a video clip to the capture window, it will play perfectly in the preview window. But if I drag the clip to the video track to edit it, it won't play. Unless I left click the top bar and wriggle it about! Then it plays very jerkily and sometimes stops. I thought it must be the program so I reinstalled it. But no better. I also have Magix Movie Edit Pro15 and a similar thing happens. I am lost. Can anybody help?
