Ok, just tried out the online ordering.
Logged into my Vudu account on the website, picked the Happening SD(just because Ive just seen it on bluray) and purchased it.
I then turned on the Vudu box and it already showed up in My Rentals. Even at 2mbps down, SD stuff is instant watch. Great thing about the online ordering is that you can pick a HD or HDX movie while at work or , for me, while out of town and itll be downloaded and waiting on you when you get home.
Just for kicks, I played the SD version of The Happening to see what the PQ was like. Id rank it slightly above DVD, not quite as sharp as a PS3 or BD30 upconversion, but about like my $90 Sony upconvert did 2 years ago. Definitely not bad for a movie in a pinch since its instant watch.
