I've tried using Replay AV (http://all-streaming-media.com/record-video-stream/Replay-AV-capture-Streaming-Video-Audio-Radio-Shows-Online-TV-Broadcasts-Video-Clips-Audio-Archives-Podcasts-Free-to-try.htm) on the following site, but it doesn't work for me.
http://www.tv3.se/play/3571

I'm able to watch the video, although it always buffers a lot. When I then try to use Replay AV, the file is not found in the cache.

WM Recorder (http://all-streaming-media.com/record-video-stream/WMRecorder-One-click-online-audio-video-stream-recorder.htm) doesn't work on it either.

What can I use?

[Stream Recorder]

Replay Media Catcher (http://all-streaming-media.com/record-video-stream/Replay-Media-Catcher-HTTP-RTMP-FLV-MP3-ripper-recorder.htm) can perfectly record videos from TV3.se
