NetStream.Play.StreamNotFound error

[patrinos]

Hello everyone, i just joined this forum to request your expert help on a rtmpdump issue.

I'm trying to download the video that appears on this page:

http://www.ert.gr/webtv/net/item/122...3#.UYncBMqBWSr

And I'm using the following command line

rtmpdump -W "http://www.ert.gr/webtv/multi-player/AkamaiFlashPlayer.swf" -r "rtmp://cp90990.edgefcs.net/ondemand/worldwide/2013/net/es-aurion-ta-spoudaia/20130407-eis-aurion-ta-spoudaia.f4v" -o filename.f4v

But i received the error:

Connecting ...
INFO: Connected...
ERROR: Closing connection: NetStream.Play.StreamNotFound

I understand this means the .f4v file is not found, but that link is correct.

Any help would be appreciated.

Thanks a lot

Dean
