I was nagged to update the MPC-HC player to the latest build (6597) but I seem to have some major problems. If I stop a video Mediabrowser sometimes stays minimised rather than popping back up which is a real pain when you don't have a keyboard or mouse to hand. I have also had instances of the video stopping but the sound continuing and the only way forward is to stop the running process via Task Manager. I notice the Reclock icon remains in the taskbar even though MPC-HC appears to have stopped. I reverted to the 6366 build and all is well again.
