Pressing the EPG button displays a list of bouquets in the "Choose Bouquet" screen.
- choose a bouquet here and the graphical EPG is displayed which shows programme information and allows the selection of a programme for viewing and the creation of a timer for recording purposes. If you press Menu in this screen you are given the "GraphicalEPG settings" screen that allows you to change the way the EPG is displayed - simple formatting mostly.
Pressing the TV (or Radio) button displays the same list of bouquets in the "(TV)" (or "(Radio)") screen.
- pressing Menu here displays a "Channel list context menu" containing bouquet maintenance options e.g. create/amend/delete so that you can maintain your own bouquets.
- choose a bouquet here and a list of services is displayed along with programme information - Now and Next and PiP, and also Satellites and Providers information.
- pressing Menu after a choice of bouquet displays another "Channel list context menu" screen which provides faciliies to maintain the constituents of the selected bouquet.
The EPG button quite obviously enables you to see EPG information.
The TV (or Radio) button provides facilities for bouquet maintenance, but also tries to be a bit EPG-ish with Now and Next and frustratingly provides better facility than the EPG in showing greyed out services due to unavailable tuners.
Why isn't the "Channel list context menu" not called "Bouquet context menu". Personally I would be quite happy if the term bouquet was dropped entirely and replaced with Service Groups and then Service List for the constituents of the group.
The TV and Radio buttons enable manual maintenance (in the context of bouquets perhaps Bouquet Arranging might be more appropriate

), a manual facility compared with the automatic function of ABM.
