Since the web-site requires registration, I can't check this for you.

You can try to install the demo version of Replay Media Catcher or Jaksta and see whether they can record the video or show any error messages.

If RTMPE protocol is used, the stream won't be recorded neither with WM Recorder, nor with Replay Media Catcher or Jaksta.

You can also try to find the stream URL with freeware URL Snooper. I can give you more suggestions depending on the stream URL (or format and protocol used).
