You could be right.  I assume softdevice wants the primary layer on top?

Unfortunately, the existing implementation of levels was broken
because it had a positive value as being below the primary.  The
documentation for SetLevel is clear that it should be the other way
around.

You'll now need videoLayer->SetLevel(-1).

You'll also need to set DLOP_ALPHACHANNEL on the primary layer to get
the behaviour you want.  This is necessary in order to support OPACITY
as an alternative.  These options will fail on earlier versions
(assuming you weren't setting DFB_CLE266_UNDERLAY) so you will need to
check the primary's capabilities for DLCAPS_ALPHACHANNEL.

You can always get a tarball from the web site if it's not:
