wapo.st: Getting Past NetStream.Play.StreamNotFound rtmpdump error

[hanmari]

Saving this stream should be a cake walk, but I can't get past this hurdle: NetStream.Play.StreamNotFound

VIDEO PAGE: http://wapo.st/o9pszv

The flash embed code is easy to read, but RTMPdump can't find the file. I have tried dozens of variations of rtmpdump command options, but haven't found the right combination yet. I couldn't get the rtmpsuck or rtmpsrv commands to reveal the connection settings on my machine, so I feel like I'm shooting in the dark. Can anyone else stream this video? If so, what magical element am I missing?

rtmpdump
     -r rtmp://cp18289.edgefcs.net:/ondemand/media/2011/10/11/10112011-92v.m4v
     --host cp18289.edgefcs.net
     --app ondemand
     --playpath /media/2011/10/11/10112011-92v.m4v
