Netflix including DD5.1 can be downloaded using Flixgrab. Just buy the license it's not expensive and is currently supported and works.
Download FlixGrab (WORKS w/ DD5.1 - need to buy)

As for Amazon it is more then just cookies, they are using Widevine 2 protection which requires duel keys (hardware & software) so no cookie hack is going to get WVD working.

I also tested flixgrab and got the same results as you. It's re encoding and cannot even give you a file with equal audio/video lengths. The audio is always significantly longer than the video. It does download very quickly, so it would appear that flixgrab is accessing the original stream, they just need to stop re encoding it.
