I have seen a lot of questions and/or complaints about not being able to view only subscribed channels with Fios. There have also been a lot of complaints about needing to use the Favorites Button. I have been answering some of those posts to help those people who only want to view subscribed channels. I thought it may be easier to put it in a specific post, so here goes:
First, this only works if you have the new 1.9 Guide. If you still have 1.8, you will have to wait.
Go to Menu, Settings, Television, and then you will see something like "Last Viewed Guide State" all the way near the bottom. Click on enable.
Then, go into Guide, hit Options, select "Subscribed," and your Guide view will stay on subscribed channels. You won't have to use Favorites again. It will stay on subscribed until you change it to something else. For instance, if you do hit the Favorites button, you will get your Favorites channels in the Guide menu. Then, you will have to go back in and select Subscribed channels. You can also set it to only view HD channels and other selections. It is up to you. With subscribed channels, you will still see PPV channels and such because you do still have the ability to purchase movies and events from those channels, but it will block out the channels that are not in your tier or that you don't pay for like HBO, Cinemax, etc.
It seems to be a long way to go about doing this, but at least it is there now.
Hope this helps.
