[quote name='movie_mike']Question - are you able to tell much of a difference between SD and HD when viewing on smaller devices like tablets or even desktops?
Also, when streaming a 1080p video to your TV, is the quality just as good as a Blu Ray or is it not quite there yet?
I'm just now getting into the digital copy game (yes I know - I'm playing catch up) because I've always felt that physical media holds up better quality wise. (bit of a snob that way) Thanks in advanced

I can definitely tell on my PC monitor which has a 1920 x 1080 resolution, The difference between SD and HD is night and day. Vudu's HDX video quality is definitely not Blu-ray quality, but it's close. On the audio side, BD has the advantage of having lossless tracks, while Vudu just has 5.1 surround sound. As for portable use, the difference probably isn't as noticeable, but it depends on the type of screen and such. I haven't really used my UV movies on my tablet though. I watch them on my PS3 in full HD.
I look at my digital collection as a compliment to my physical one. I'm not planning on replacing my physical one with a digital one anytime soon. Ultraviolet copies (which I buy from people for $2-3 at Blu-ray.com), and this disc to digital program comes in handy though when I don't feel the need to buy the Blu-ray, but still want to watch an HD version of something. Blu-ray trumps it ultimately because of the better picture and sound, and just as important for me, the extras, but the digital library is a nice compliment to it.
