I want to capture the video streams using the RDP 7 video redirection featu

I am exploring the video redirection feature on the RDP (Remote Desktop Protocol) connection on Windows 7. I would like to capture the audio/video streams before it is displayed by the media player. I need help from you guys on how to go about it.

The approach I am thinking is whenever remote session is established using mstsc.exe and the user selects video file. I just spawn a new application which captures the stream of data been used by the Media Player. Any other useful inputs would be of great help.
