I understand you are having audio and video issues when using S-video and composite cables. In order to provide you with troubleshooting steps to assist you, we will need a little bit more information on your set up.
First, are the S-video and composite cables connected to the same source simultaneously? Secondly, what is brand name on the power supply that came with the Slingbox? And lastly, if you run the composite cables directly from the cablebox to the television, do you get proper audio/video?
Awaiting your reply.
