Video not restarting on return from activity with an Android element HUD

I've got a version of ImageTargets and incorporated all the elements from the Dominoes project to display Android GUI objects. This works fine except when returning to the activity after starting another activity, the video doesn't restart. I've stripped ImageTargets right back to the original and only incorporated these. mGUIManager = new GUIManager(getApplicationContext()); mRenderer.setGUIManager(mGUIManager); then when it receives updateApplicationStatus APPSTATUS_INITED addContentView(mGUIManager.getOverlayView(), new LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); Even simply incorporating these is enough to stop the video from restarting when I return to ImageTargets. Am I missing a key piece of functionality somewhere?
