Not able to stream a RTMP link

[sasagr]

Hello.

I got an rtmp link for live channel that I could watch using Livestream addon on my Xbian/XBMC but some some reason it works on XBMC Windows but not on my raspberry.

Better to say that it seems to be playing (I see action in the timeline) but there is no video and audio.

For the ones who want to try here the xml code of the link:
<item>
<title>Sky TG24</title>
<link>rtmp://cp49989.live.edgefcs.net:1935/live/streamRM1@2564 playpath=streamRM1@2564 app=live pageUrl=http://tg24.sky.it/tg24/diretta.html swfurl=http://videoplatform.sky.it/player/videoplayer_live.swf tcurl=rtmp://cp49989.live.edgefcs.net:1935/live/streamRM1@2564 live=true timeout=40</link>

Hope somebody can try and tell me if it works with Xbian or not because with mine it does not work

Thanks in advance
