If advertisements play but shows won’t, followed by an error message either saying ‘Video not playable at this time’ or ‘Processing DRM failed’, please try the following.
Head to the Android play store and search for ‘DRM Info’. Download the first two apps to be suggested. The first should be by Android Fung, the second app by Roman Hosek.
Please run both of these apps. One of them will tell you specifically whether Google Widevine Modular DRM is supported or not, while the other will say which ‘available engines’ your device has, which should be something like ‘Widevine DRM plug-in OMA V1 Forward Lock’. Please let us know whether your device supports Google Widevine Modular DRM, and what available engine your device has.
