I have an HD DirectTivo, and I am having a problem setting the "Channels I Receive" list. I recently had to re-align the dish, and since then I have not been able to remove those pesky shopping channels! The guide always shows me all the channels. When I go back into setup for Channels I Receive, all the channels are checked. I have the guide set to show me only "Channels I Receive", and I have been testing by "unchecking all channels" then just adding a few back in. I have restarted (but not a delete everything/restart). Is this a known problem? Any solutions or workarounds?
