You have the one i have. The one in theaters with its original soundtrack/dialogue. Ima watch it tonight but i skimmed through it and the score is 80s music and its all in sync.
Its the h264/MKV version thats supposedly incomplete or different.
Some of these people commenting on the screener on other forums have seen the movie once in theaters but somehow remember the smallest details about it and every difference between the theatrical release and the screener they have lol.
yeah it gots the 80's music, and its in sync, and the quality is pretty great for a screener, but a lot of scenes has the Social Network soundtrack instead of the one for Drive. but im reading that its like that becuase it is just a workprint and studios do that all the time.
it just stuck out to me like in the scene where Standard is telling his son how he met her mother, it is playing that opening song from Social Network.

also, on the CGI, it wasnt complete. like in the scene where Blanche gets her head blown off, you see the blood, but her head is fine, all you see is her hed move. thats the only part i noticed, but i havent seen the whole screener yet
