My two cents (From a Hard Target/JCVD Fan):

Video/Audio - almost flawless, notieced at the start the Audio was low with the machine gun shots before a small building explodes as her dad is rolling down a hill, I kind of remember that from the original version too though. The new video scene (I think) where JCVD and Yancy are in the bar looked great as with the whole movie and every frame looked as good as they could be to me.

The main differences I remember from my screener copy which I finally viewed last summer are the scene where the police lady, Kasi Lemmons, dies (seemed much more emotional, read that she recieves more wounds and he fires way more back at the killers), then the piano scene cut with the African hunting footage, the Arnold Vosloo character trying to convince Lance Henrickson that they should walk away near the end (more realistic and convincing), and then all the somersaults!!

This version didn't have the more powerful scene of the police ladies attack, the piano scene didn't intercut the animal hunts, hmm, Arnold Vosloo wasn't trying to convince Lance Henrickson like in the screener, but I'm really happy it didn't include all the somersaults!! I only counted three (well timed) ones here instead of the 15 or so from the screener!!
