Someone in the FlashComm list just pointed out this really good thread at macromedia dealing on how to use Camtasia to capture your screen for streaming with FlashCom. Just gave it a try downloaded the trial version and found it really usefull plus very easy to use. Although for live capturing it would only allow you a maximum of 320x240 resolution, it could be used for higher resolutions when recording to a file and converted to .flv for streaming later.
