If you want to use streaming media recording software for Windows, you can try to run Windows applications with WINE emulator. Some programs work just fine in WINE:

• How to install and run Replay Media Catcher in Linux (Ubuntu 9.10)

while I didn't manage to use the following programs:

• WM Recorder - problem running in Linux with Wine emulator
• GetASFStream - problem running in Linux with Wine emulator

Please note streaming media recording software for Windows that you run with Wine, can detect streams only from web-browsers and players that you run with Wine. So you need to launch a Windows web-browser (Firefox for Windows, Opera for Windows, Internet Explorer for Windows) with Wine to record with Replay Media Catcher from it.

Alternatively you can install a virtual machine like free VirtualBox, the install Windows onto the virtual machine and use Windows software on it.
