twitch.tv: How to find and play rtmp urls?

[chobo]

Hi,

I am a complete newb at video streaming and such. I am trying to find rtmp urls from sites like twitch.tv and ustream using url snooper, so I can better understand the technology and learn something.

I usually find what I think is the rtmp stream, but when I put it all together into a url and try playing it in an flv player (I'm using Moyea flv player) it doesn't work.

For example If I go to the following stream (random game replay)
_http://www.twitch.tv/playhemtv

I get the following with URL Snooper:

rtmp://199.9.255.51/app/jtv_FCaJ4C1HEYq_z_LR


If I use RTMPexplorer and navigate to it I get

rtmp://199.9.252.8/app/jtv_d1pr07Hj2R_v6kuF.flv


If I use either of those two urls for the streaming url in Moyea FLV Player it just shows a black screen. What am I doing wrong?
