Have NFL Sunday Ticket? Watching it on a PlayStation 3? Sorry, are you attempting to watch it on a PlayStation 3? Apparently it isn't working very well. DirecTV is currently "troubleshooting" and a number of key features are deactivated. [DirecTV]
Mine didn't work at all. I also had some issues with my DirecTV feed as well, but my main TV worked almost the whole time with an occasional glitch, while my PS3 never even loaded any games. It sucked, I was looking forward to having a two TV Football Day.
