Videos for movie maker?

Hi, as I know, Windows Movie Maker supports wmv and mpeg format video files well, so you need to use a right software to convert your mp4 files to right wmv or mpeg files for windows movie maker, but I don't think there is a free converter can do that well, because I have tried many free softwares, none of them work well, some of them have many limits, some of them are poor quality, some of them even have virus, so now I'm using a cheap software RZ Video Converter to do that, it can convert any video files and audio files between different formats, such as convert your mp4 files to right wmv or mpeg files for windows movie maker without this problem, yahoo or google search and download RZ Video Converter, hope it can help you.
