I was having these exact same problems then I noticed that my tv had not updated in 2 days. Did manual check and there was an update from 9.4.2 build 4063-AT to 9.4.2 build 4101-AT, fixed everything. I hope it helps someone cause I was just as upset as everyone here.
I did numerous manual updates on yesterday till 7pm PST, but haven't tried today. I will try at my earliest convenience and add comment with my results. Probably will not be until tomorrow though. I really hope fixit's fixed. 4 days without live TV is unacceptable.
