In WIndows Movie Maker (WMM) I Can D Up To About 5 Seconds Of Clips Before It Goes Insane And Jumpy / Freezing / Un-Responsive. I Can Do Anything Like Slide shows Or Text For As long as I Want, But When It Comes To My Clips It Just Cant Do It.I KNOW there Supported File Types, Ive Made Videos Before. I Cant Download Anything, Other Than Movie Maker / Msn Developed Things Because My Computer Is Quite Sensitive To Virus. Please Help Me, Im So Annoyed at It! Or Is there An Alternate Thing I Could Use? Ive Used Corel, Witch Is AMAZING, But I Cant Really Pay For It :/ Please Help Me Fix This!
