You should read the code in: xc/programs/Xserver/hw/xfree86/common/xf86xv.c
in order to understand the architecture of Xv. This is the di part of Xv. If you properly implement the dd parts of Xv by populating the dd function pointers in the adaptor section with routines specfic to your device I think you will discover your driver will be notified to stop/start video, save/restore state, etc. all at the right moments. When you say your "Xv code" I trust you mean you are implementing the dd part of Xv in your driver and not trying to implement Xv at a level higher than the device.
