The Xilisoft FLV converter sounds like it might be a perfect match for your needs. This converter is not free, but there is a trial version available so you can check it out to see whether it is right for you without paying anything.
Im trying to convert my video which is a FLV to a file type that is acceptable for Windows Movie Maker.
This are the valid files for Windows Movie Maker- .asf, .avi, dvr-ms, .m1v, .mp2, .mp2v, .mpe, .mpeg, .mpg, .mpv2, .wm, and .wmv
I just need help converting my FLV to one of these types of files.
