Go to http://www.virtualdub.org and download a copy of the latest version. It's a great little freeware program that will put Windows Movie Maker to shame once you get the hang of it.
Before I installed SP2 on my machine I used the latest version of Movie Maker 2.0.
SP2 comes with an upgrade of this software from Microsoft.
After installing SP2 Movie Maker now will not completely load and stops with an error that will not let it continue loading. Has anyone experienced this problem?
