How do I rtmpdump a PROTECTED flash rtmp and embed it to my own website?

I have read just about every thread on here that is similar to this, but I still cannot figure out how to do it. I would like to know how I can rtmpdump a PROTECTED rtmp flash stream and embed it to my website... I have the FLV, I have the RTMP code. It is really upsetting me due to the fact that I've been trying to do this for the past week, and I just found this website.. I used this code:

Code:

rtmpdump --live -r "rtmp://91.121.81.15:2195/live/?rtmp://217.23.8.232:2195" -o "C:\ch10.flv"

I had this error:

I run Windows 7.

Thanks in advance to anyone that is able to assist.
