 To danielk

 I totally agree. The use of the m_surface is a bad ideal. I checked to see
 how the other closed caption routines work and all of those have a
 callback to the osd to schedule a draw request. This callback is normally
 made via NVP but since the DVB teletext is separate you might still have
 to provide a osd reference to use. So using the work you have already
 started and adding double buffering of the data and a callback to request
 a redraw should work.
 One other issue that might have to be addressed is the order in which the
 OSD does a redraw. The last thing you want is for the teletext to be the
 last item drawn. If it is then all other OSD is hidden (since drawing a
 blank teletext page actually clears all other data). The current version
 that make use of the m_surface variable has the effect that if I display
 the menu and then get a new page of caption it hides the menu.
