I recorded a game with Dxtory and put it into Camtasia Studio 8 to edit it. I proceed as normal and when i pressed the play button it kept freezing the video and the audio was jumping on the same spot kinda like a scratched CD. I monitored my GPU, CPU and RAM all were fine! I then tried a video with windows media player, that had similar symptoms. YouTube works absolutely fine. Camtasia then crashed but fixed itself... What can i do?
