There is an issue with the slingbox pro HD and the apple app. When using the AirPlay feature on Apple TV only the audio comes thru but no video. This problem seems to be limited to owners of Slingbox Pro HD, one of the original models. There have been many discussions in the forum and the last app update did not fix the bug. For all owners of this type of slingbox its my guess you were buying what amounts to a radio!!! HELP!!!
