Replay Media Catcher is a flash stream ripper. It can automatically record .MP3 audio and Flash .FLV streaming video broadcasted through HTTP and RTMP protocol (such flash stream URLs start with http:// or rtmp://). I highly recommend it.

FLV Recorder is a flash stream capture software that can record .FLV video streams through HTTP and RTMP protocols.
