Welcome to the Forum.
Unfortunately stating â€œPowerDVD Will Not Play The Video From The Video Storeâ€ does not provide any meaningful information for Forum Members to be able to analyze exactly what is occurring. For Forum Members to provide assistance you need to explain in detail exactly what happens when attempt to use PowerDVD to play/view the undisclosed â€œDVD from a video storeâ€. If any Error Notifications are displayed provide the exact complete narrative of the Error Notification.
The fact that your Pioneer DVR-111D is able to view â€œSomeâ€ DVD Videos indicates that that your Pioneer DVR-111D is functioning correctly and indicates that your problem lies somewhere in your video viewing/playback software program.
You ask â€œHow Do I Change My Defaultâ€. Unfortunately I do not understand exactly what you are referring to. Perchance are you referring to setting/changing your Pioneer DVR-111D and/or PowerDVD Software â€œRegion Codeâ€ setting?
