How to record rtmp from TotalReality.tv?

[StevenRobertson]

For example, let's say that I want to record http://totalreality.tv/utopia.php

I'm absolutely stuck. The most successful attempt was this, which resulted in an error:

rtmpdump -v -r "rtmp://173.193.197.46/flash/B19573?MTQxMTMzODgyNjs3ZTMyMDA2NGIwOTA1ZTZiNmExMTBmNjgwZjU0MmJhNw=="

which resulted in an error:

ERROR: rtmp server sent error
ERROR: rtmp server requested close

I'm new to rtmp scraping. I used wireshark and captured the following
