I see that this question comes up about every two years, and there is no better solution than individually blocking channels.
I beseech Cox to contact their competitors and make this part of their programming options. Other cable media companies have figured out a user-friendly solution to filter out unsubscribed channels from the guide, or at least gray them out so you can skip past them easily.
so far, this is our biggest complaint with this cable service - sorting through dozens of channels to view the ones available to us.
What you could do is set all your subscribed channels...or at least the ones you like...as Favorites and default your Guide to only show Favorites (click Guide button twice).
I don't know if there is a limit on Favorites. However, you're correct, the developer should have a Subscribed option.
Isn't that what the "Free to Me" option does?
