Several ways to play FLV files

• Playing .FLV videos with freeware Applian FLV Player
  1. Install freeware Applian FLV Player
     
     If you already have Replay Media Catcher or Replay A/V installed (it can be used to record .FLV videos easily), then FLV player is already loaded for you.
     
  2. Locate the FLV file using File Explorer. If you've used Replay A/V, click the Show you've captured, then click the View button.
     
  3. Double click the .FLV file. It begins playing in FLV Player
  This is the most stable .FLV playing solution I've ever tried.
  
• Playing .FLV videos with freeware KMPlayer (MPlayer)
  
• Playing .FLV videos with freeware VLC Player
  You may also use VLC Player instead of FLV Player to play .FLV files
  
  VLC has problems playing some FLV files.
  
• Playing .FLV videos with Windows Media Player, Media Player Classic using a codec pack
  The latest version of K-Lite Codec Pack (freeware) has FLV splitter. You may play .FLV videos after installing it using any DirectShow-supporting player like free Media Player Classic or even Windows Media Player for playing FLV files.
