How can i Convert fLv to dat file?

I use a program called FLV Editor Pro which can edit FLV and convert FLV to other video formats like avi, mpeg, mp4, mp3, wmv, mov, 3gp and so on. You can use it add watermark, merge flv, trim and crop flv and add special effects. Most important point is that it can output FLV without recoding and repressionflv converter or FLV encoded with H.263. I think the AVS Video Converter is your best choice,It alway works well for me.
