Like many people, I've been down for almost a week. I'm using the IKS66 specific STB Emulator and noticed last night that some channels went up. A lot more are back this afternoon. For comparison, if anyone is interested, these are the (English) channels that are up for me, no buffering or freezing. I'm gonna start backwards with the sports channels since that is important to many people.
Edit: So a lot more channels went up for me WHILE I was doing the list, it would now have been better to show what ISN'T working but it's too late now. It's important to note sometimes it takes a while for them to kick, particularly if switching from a channel that's NOT working.
