I have made a few flights with this aircraft and I'm having some problems to reduce speed while on descent.

I have changed to SPD mode, reduced manually to, let's say 150 knots on MCP, activated speedbrakes and descend on a 1200 ft/min V/S. Of course I have VNAV disconnected so CDU speed does not influence.

There is no way to have the aircraft reduce its speed!

Someone else is also having this same problem?
