Silverlight player allows to play Windows Media streams and Smooth Streaming.
webtv.tv2.no uses HTTP .wmv Windows Media streams. For downloading Windows Media streams I recommend to use
WM Recorder in the ADA mode, freeware
GetASFStream or
SDPReceiver.
For capturing Windows Media streams from your local Windows Media Player I recommend to use
WM Recorder in the PRO mode, or freeware
WebVideoCap.
But in this case many other programs will work just fine.
