www.cmt.com: problems downloading rtmpe stream

[cadogan]

i tried to download a video from cmt.com with rtmpdump, but it stops everytime, even with resume.

here is the stream:

rtmp://cp3547.edgefcs.net/ondemand/mtvnshrdstor/_!/mtvi/bands/a/adams_ryan/ryan_adams_september_epk_240.flv

this is what i type in on the cmd prompt:

C:\1>rtmpdump -r rtmp://cp3547.edgefcs.net/ondemand/mtvnshrdstor/_!/mtvi/bands/a
/adams_ryan/ryan_adams_september_epk_240.flv -o ff.flv --resume

and this is the error i get:

C:\1>rtmpdump -r rtmp://cp3547.edgefcs.net/ondemand/mtvnshrdstor/_!/mtvi/bands/a
/adams_ryan/ryan_adams_september_epk_240.flv -o ff.flv --resume
