I setup Orb and Audible on my PC. When I double clicked an AA file on the PC it opened in windows media and played. That is how I knew setup was correct. Then I attached to Orb by going to MyCast your digital media with Orb 2.0 remote pc access software on my HTC Hero, put my username and password in and selected the audiobook I wanted to hear. It started streaming in the video player without a hiccup.
