I have just been upgraded from the ELMO TT-02s to the ELMO TT-02RX. I am trying to use it to record video. I know it can. However, the instruction manual isn't much help. It shows an optional desktop recorder. Do I need that? I can't even find where to buy one. Can I use a web based solution? I have installed the new software. I seem to be recording but it only plays back a few seconds. Help!?
