When I have my slingbox in 'pass-through" mode (watching live TV), the audio is out of sync with the video feed on HD channels? I have tried looking through all the online support don't see any answers with my problem. Anybody have my same problem? Maybe its just a reality of the technology of the box. I have Comcast Xfinity and decent internet speed, so I don't think it has anything to do with the cable/internet speeds. Any help would be greatly appreciated.
