Since AirPlay came to the Mac, DVD playback has always been blocked due to supposed "DRM issues" (whether or not the DVD's themselves even impose any). I could just use an HDMI cable instead of paying an extra $100 for an Apple TV and achieve DVD playback with no "DRM issues" at all. They now advertise that AirPlay mirroring will act more like any other external display. So, simple enough question... as with any other external display, will DVD playback be allowed???
