I know there are many threads on this topic, but thought I'd add another one with the hope that Vudu will eventually be compelled to catch up with the competition.

I currently own 115 UHD movies on iTunes and FandangoNow that are NOT available in UHD on Vudu. That is a huge difference! And this is just my personal collection. The discrepancy is much larger when considering all movies available in UHD.

The pace at which Vudu is adding UHD to movies is so slow that I don't have any confidence they will ever catch up. Besides my large investment in Vudu, I also really like them, and therefore I want them to succeed!
