The Home page (FreeviewPlay) will display right after the usual Netgem TV startup screen. There you will see your last played channel, with a "live preview" of its current programme in the background. On the top-left, you will have the programme's information displayed.
The first row of the FreeviewPlay area, "Now on TV", is where you will see the current live programme on each channel. A tile for the programme guide can be found at the start of this row but you are able to access it from the "Guide" button on your remote too.
The second row displays the on-demand Freeview apps such as ITVX, Channel4, BBC iPlayer, My5, etc. Most of the past programmes from live Freeview channels will be found within these apps.
Rows from "Freeview Play" onwards will contain on-demand programmes grouped into themes or genre-based rows.
Once you select a programme from these rows, you will be taken to a page with a full list of available episodes. From there you can select another episode that interests you and play it or add it to your watchlist. Check the "My TV" area for programmes added to your watchlist and access them whenever you like.
One final tip before you go, you can easily access the FreeviewPlay area by pressing the "Home" key on your remote control.
