I noticed that you are not able to watch any of your TV programming using your Slingbox. This problem can be caused by the receiver that you have connected to the Slingbox. In order to determine if that's the problem, connect another AV source to the Slingbox and test it out. If the issue persists, then you will need to troubleshoot the AV source itself, not the Slingbox.
