Hi Chip231 -- I can help with your subscription issue. Playboy is a channel that shows up in the guide regardless if you subscribe to it or not. If you've unsubscribed from it then it should give you the same "Subscription Needed" message if you try to select it. Can you try that to see what happens?
For Dog TV and Anime Network, does this happen on each box you have? You may need to refresh your boxes to refresh your credentials. Please unplug the coax line and power line for 20 seconds and then plug back in.
