Do you get any air flow in that room now, is there room under the door for air to get out of the room and back to the return.
Poor location of return air can have something to do with it.
Framing in basement can make it difficult to run ducts, beams and such can make the installer add to many elbows making the duct act like it much longer than it is.
Any way you could add a return air vent to that room.
Return air usually runs between floor joists if you can figure where it is and if a wall crosses it, it gets easy.
