You can find your subscribed channels in “Favorites”, but you need to tell the Guide to remember it. To have the Guide remember your Subscribed channels, press MENU on the remote, go to Settings, over to Guide and choose OK. The Guide settings will come up. The third option is: Remember Channel Filter. Change that to YES and then arrow down to the bottom of the screen and choose SAVE.
Then, the next time you’re in the guide, choose the Subscribed channel list by using the BLUE button for Favorites in the colored row. Now your set top box will remember that selection anytime you open the guide.
