I knew as soon as I saw the thread title, before even reading the thread, that the OP must have Eastern Arc. The problem is that for most unsubscribed channels, if they show up in the guide at all, only the standard-def feed is visible. The HD feed of most channels is always hidden unless you subscribe to the channel, or it is in free preview. This complicates things because on Eastern Arc, many national channels, including most of the premium movie channels, no longer have SD feeds, not even with the full Eastern Arc including the 77 satellite. (That is where most of the remaining Eastern Arc SD feeds can be found.) So, with no SD feeds, the channels completely disappear on Eastern Arc when you are no longer receiving them. Meanwhile, on Western Arc, the Epix channels (for example) are still listed as green in the guide for non-subscribers because they still have SD feeds on Western Arc.
