Default [Q]Can't watch Google Play movies in AOSP

Any idea on Error code -12 when trying to watch a movie via Google Play Movies on my device (Razr HD and Nexus 7)? This seems to only occur when I'm on a KK AOSP ROM (CM11 or Gummy). I can cast it to my Chromecast, though.

If I go back to stock, it works fine.
