Well it looks like GyaO got to air it (Druaga) first at 25:15. YouTube Japan, CR and BOST TV don't have it yet. CR's count down says that it's over an hour (1 hour 46 min) to showtime.
The free promotion was for the DRM free download of ep. 1 in addition to the rental. It couldn't hurt to give it a try.
Edit: That would put the broadcast time
according to CR at 27:00, just 1/2 hour before TVHokkaido.
