Movie maker vista problems?



I have a friend who bought and updated his dell vista home to vista sp1. But he had continunining problems with movie maker in vista? When he drags his homemade movie file to movie maker it just hangs. I know cause I tried this on my movie make xp machine and it works just fine? I also did drag and dropped a video file into movie maker xp and it configured it perfectly? Is he missing something or what?


Thought I bring this back to the fold to see if anyone else has found this problem occuring with Vista???
