How do you convert a flash video into avi or some other format?

have a lot of flash videos that I want to convert to another format that would be playable on my lg vu cell phone. I uploaded flash videos onto my cell phone and it doesn't work. So how do you convert a flash video into another format? You should convert your flash videos to 3gp flv compatible player videos, most cell phone only play 3gp videos,moyea flv downloader I have used RZ Video Converter, it can convert any videos and audios from one format to another format, such as flv to 3gp, etc. work well on my computer, Inexpensive, i like it.
