It's working fine to me. I got stream info with rtmpdumphelper.
Code:
rtmpdump -r "rtmp://199.9.255.172/app" -a "app" -f "WIN 11,6,602,180" -W "http://www-cdn.jtvnw.net/widgets/live_site_player.r37889147b85993632c055354534158a802e30b80.swf" -p "http://www.justin.tv/twit#/w/5272587344/73" -j "090d713c5cb4785c8c25abf597592d727e9e08f9:{\"swfDomains\": [\"justin.tv\", \"jtvx.com\", \"xarth.com\", \"twitchtv.com\", \"twitch.tv\", \"newjtv.com\", \"jtvnw.net\", \"wdtinc.com\", \"imapweather.com\", \"facebook.com\", \"starcrafting.com\"], \"streamName\": \"jtv_r01_Eta3RPwfDCMO\", \"expiration\": 1365069162.823472, \"server\": \"video8-1.ams01\"}" -y "jtv_r01_Eta3RPwfDCMO" | vlc -
