Hey Bender, when you check your friend's disc, can you make photos of the discs and cover? I wonder if there are indeed two different versions of this out there, with different mixes (or perhaps faulty tracks) on them.
Sadly, it appears there is no real 5.1 edition...
Here is what I found out after much time on this issue....
Issue ... My DVD copy of this is 4.0, not 5.1 as advertised. My DVD-A copy I made for the car has all 6 channels. So, how did this happen???
My initial thoughts were I had possibly ripped the tracks from a friend's copy of the DVD and theirs was truly 6 channel. (in my early days of this I needed to use a PC as I had not discovered a way to do this on a Mac-- so maybe that is whappened.
Answer - No, all three copies are 4.0, mine and the only two sources I could have gotten the tracks..
However, I remember when I made my car copy, I had initially forgot to cut the extra "artistic direction" that is on Listen Like Theives, Mystify, Suicide Blonde, and Need You Tonight. So I had redone it somehow.
When I make a 4.0 DVD-A from the DTS DVD and then extract the audio using DVD audio extractor, it somehow creates the other two channels. Definitely not discreet, but still sounds way better than the straight 4.0 mix, that is labelled as 5.1 surround.
This makes no sense to me whatsoever, but I have thrice tested now, and this is indeed what is going on.
It's still a great DVD collection. Strongly recommend, but I am not sure what the issuer means by remixed in 5.1, if all we get is 4.0.
If anyone can add to this I would love to know what's happened with this one.
