How to download from mubi.com? (possible rtmpdump bug?)

[splendor]

I'm trying to download this movie:
_http://mubi.com/films/the-new-environmentalists (I guess you need a free registered account to see it)

With pmdump I figured the rtmpe url is:

rtmpe://theauteurs.bc-s.cdn.bitgravity.com/cdn&versions=&defaultVersion=&videoOffset=&id=91271&type=film&preroll=&autoload=1&autoplay=1&debug=&ap=1&useStageVideo=1

But when I try this:

rtmpdump -r "rtmpe://theauteurs.bc-s.cdn.bitgravity.com/cdn&versions=&defaultVersion=&videoOffset=&id=91271&type=film&preroll=&autoload=1&autoplay=1&debug=&ap=1&useStageVideo=1" -o movie.flv

It says:

ERROR: You must specify a playpath (--playpath) or url (-r "rtmp://host[:port]/playpath") containing a playpath

I think I understand what's the problem here.. notice the strange URL:

rtmpe://theauteurs.bc-s.cdn.bitgravity.com/cdn&versions=&defaultVersion=&videoOffset=&id=91271&type=film&preroll=&autoload=1&autoplay=1&debug=&ap=1&useStageVideo=1

Because when I do /cdn/& instead of /cdn& it does work, however it says Stream Not Found, which makes sense because I changed the url.

So is there another way to tell rtmpdump what the URL is and what the arguments are?

I guess rtmpdump just has problems with this URL. I'm really sure if you can call it a bug though, because after all this is just a very strange URL.

Any one know a work around?
