A/9 / V 8 but read everything to see why... I downloaded this even though I already have the Blu-ray edition. BUT I thought I'd back mine up with this one. Well maybe... Turns out the uploader set it to play back in WMP(or at least that is what my system read it as). This is okay but the sound is really low, tried it in VLC and prefect. The sound was great. But there is slight quality difference between the original and this. Seems almost grainy or a tad off at many points. I decided to be fair and do a side by side test. Original in the Blu-ray player and this version. Stop at different scenes and I was right. Wish I was wrong as I'm sure the uploader put a fair amount of work into this. As a result the Audio get a 9 and the video gets a 8 from me. However should you wish to see this movie and save the $20 dollars then this is the way to go. Because most people aren't watching this a plasma screen and aren't going to be quit as hard about their judgement as I am. I just feel it is fair of me to be honest and give a good detailed report of what I found.
PS (Small spoiler alert here)
There is a scene that caught my attention, maybe I'm wrong here but when Ron, Hermione and Harry first arrive ion London after the wedding and slip into the alley to change I'd swear Ron calls Hermione by her real name - Emma..?

This is real. This is HD. This is good. No pixels. Nada. Nothing. And sound is brilliant.

10/10 Perfect quality!! :D
