Thanks for your post Ccargo.
Try to do a quick update on your Roku by going to Settings > System > System update > Check now.
If the issue persists from one channel after attempting the suggestions above, videos from other channels play fine, contact AMC's customer support team to report the issue and get help. Channels on Roku are maintained by the channel developer themselves. In this case, there's likely an issue within that specific channel that needs to be addressed with an update from them.

Since this is a premium channel to which you subscribed through Roku, "Remove channel" will be replaced by "Manage subscriptions". Click this and follow the prompts to unsubscribe from this channel. (Don't worry. You'll still have use of it for the balance of your pre-paid subscription period. You can resubscribe later if you like.) Now the ”Remove channel" menu item will be back and you can remove the channel.
I did finally go thru the hassel of removing AMC + roku channel and resetting the device. After all of the time and effort the AMC+ Roku channel still does not show the AMC Live channels on the menu. I downloaded the AMC+ channel on a promo and their channel does, although without the preview of what's playing at the time. I will use the Roku Left menu for Live TV Zone to get to them fairly quickly.
I wish Roku or AMC would return them if they removed them. If other people see the listing then my issue was not fixed.
