Biggest problem I find with VUDU is the 3D content is inexplicably limited to so very few devices. I like the quality of the 2D streaming but even though I have it running through a "3D compatible" device (PS3), it somehow won't pass the signal to my 3D projector - saying, no 3D supported display detected. SO, it let me buy the movie (it saw the PS3), but won't pass the signal to my Epson 6010 3D projector. So now I have to wrangle with Vudu to get a refund. But worse, I can't believe their software is incapable of simply passing the signal to the "authorized" PS3 and let it pass the signal to any 3D display. Requiring BOTH a receiving device AND a specific brand/model of 3D display is ridiculous. And costing them money.
