I'm not sure about the why - might be worth a call or e-mail to Outlaw. As an interim work-around (a sort of "non-solution" solution), you can go into the setup menu, go to INPUT SETTINGS, go to the DVD input, and change OSD from ON to OFF. It will disable the OSD pop-ups for that input at all times, which may not be desirable in your case but will at least avoid the nuisance pop-ups while Outlaw gets back with you.
