I have problem recording this stream with WM Recorder 14.1. I get an error of parsing RTMP stream (no video and audio found). RTMP recording is becoming better and better in WMR. It should be improved significantly in WMR 14.2 which is being tested now.

Try software that can capture RTMP packets from flash player such as Jaksta (switch from downloading to recording) and freeware Orbit Grab Pro toolbar.
