For over three years I've had AMC HD (261) as part of my TV package (called Personal TV + Extreme on my bill). A couple of months ago, I stopped having access to it - it now says I need a subscription service. Nothing else has changed and I still have access to all the other HD channels that I always have had. I do still get the SD version on channel 53, but I never watch anything below 200 anymore. What changed and why just this one channel? Anyone else experience this? The new Walking Dead series is staring sometime this summer.
