If you Go to disneymoviesanywhere.com and go to your profile and checkmark Amazon,Google play, vudu, ECT it will then transfer to Vudu. So if you have a DMA account and link all them it will port directly over to Vudu. I never use DMA/DMR if I get more than one copy I redeem Google only and they transfer over to my Disney and Vudu account.
No only if you redeem it on Google play and you link your Disney account together. If you go to disneymoviesanywhere.com and you checkmark all the boxes in your profile amazon, vudu, Google play they will link over to all account including vudu
