MAXNUMWINDOWS=7 is the maximum number of areas that FF DVB cards
support. VDR however uses a more abstract interface that supports up to
MAXOSDAREAS=16 different areas, provide that the OSD device can handle
them. To know the real number of supported areas, you have to do several
calls to CanHendleAreas.
Unfortunately, VDR does not enforce MAXOSDAREAS itself, so you may be
able to call SetAreas(...,100) on a very flexible OSD device, which will
probably lead to a solid crash due to non-handled cOsd internal buffer
