Streams (including Mikogo, TeamViewer, etc.) - technical aspects.

Please advise, I want to stream not on Justin.tv but on Twitch.tv – the interface is better, but I can’t, because when I enter my Twitch account and password in XSplit, it says that such an account doesn’t exist, and to check the data. Everything works fine on Justin.tv, but I don’t like it:( P.S. And, yes, another question: how do I save videos on Justin.tv? (just in case I can’t get Twitch to work) – that gear icon isn’t there.
