Finally an anamorphic version in the correct aspect ratio 1:85:1!! Right off the bat I could see it was brighter with better color, the resolution was decent, a clear improvement over the awful DVD although you can see that the source it was mastered from was less than ideal. Sound is Dolby Digital (not Plus) stereo and still sounds a little harsh, again going back to the master. Wife (and I) are happy with the upgrade.
As far as your other questions posted I don't think anything other than what is purchased for upgrade at Walmart will show up in your VUDU account. When I linked to UltraViolet and I could see the 3 DVD upgrades plus after joining the Sony UV website and entering the code for my Drive Blu-ray afterward I could see all 4 movies. I added the Flixster app to my iPad and was able to stream the Drive movie plus it's available for download. It would be nice if Flixster played my UV movies through my WD TV Live streamer but then that would defeat the Walmart/VUDU model to make you pay for a Blu-ray to HD streaming version.
EDIT: I just received my Ghost Protocol Blu-ray and entered the code on the Paramount URL provided. It showed up in the UltraViolet account and in my VUDU account as a Promo/Own - SD version.
