They changed the terms of use after I amassed a library on their site so that you cannot stream HD except on MS Edge/Safari and not Chrome. That isn't Kool. The MS Edge platform is not stable enough - buffering, constant refresh required, sound and picture don't match.... And it isn't my bandwidth either (200Mbps down). Otherwise, VUDU is Ok. Streaming 4K is only possible on 4K devices - but not your computer even though my computer is 4K. Same network and we do fine on 4K.
