I have Windows 7 and am currently using Windows Live Movie Maker version 15.4.3508.1109. I have a .wmv video that I added to my movie project then trimmed a portion of it. When I play the trimmed portion, the video pauses momentarily within the clip then begins playing again. I'm not sure what is causing it to do this. Is there any way to stop this from happening? It's so annoying! Any help will be greatly appreciated!
