I have some tv shows downloaded that I'd like to watch on my HDTV. I currently have a Mini DisplayPort to HDMI Adapter and a 3.5mm male to male audio cable that I plug into the TV and the headphone jack on my MBP. 1. The audio does not work. Is there a setting somewhere I must enable? 2. Would I be better off buying some other sort of cable? 3. What are my options for displaying my MBP screen on the TV and where do I access these options? When I hook up the adapter it just extends my screen to the TV. Perhaps I need a MBP to TV guide of some sort. I can get this done easily with my old PC but I"d really like to do it with my MBP.
