Streaming radio DJ'ing

[Ringo]

Hey guys.. I've a problem thats been driving me nuts all day. I'm trying to record an mp3 mix, an hour long, to be broadcast on streaming radio.

The problem is, that I want to have two copies of WinAmp open, and mix the songs that way. I've been looking for applications that can record this output, but none can do it.

What software are most internet-dj's using these days, and is there a cheap way to record the sound that I'm looking to record?
