My Goodmans GDB12XIT has the same problem as the Dion. Pages that have not changed much, e.g. Weather, mostly seem to work, but other pages lack the buttons at the bottom of the menu pages and drop back to the TV when any page is selected.
It should be noted that this box always has had a problem in that it frequently forgets the page numbers, particularly if the previously watched station was also a BBC station.
However, if they can get it to work, I like the full screen news pages.
