If you link your Vudu and Ultraviolet accounts, the UV movies show up in Vudu under the My Vudu tab. Its only an SD, Dolby Digital stream though.
Thanks OP. Picked up both MKs and Justice League Doom.
I've ordered four times using Google checkout. Each time I received a confirmation from GC but never any shipment notification. Packages arrived 3-5 days after ordering.
