I was going to make a thread about this when I stumbled upon this one. I too have been searching for the CDS mix and ended up getting a hold of the original LIVE 1998 R1 DVD. While it does sound great how can we be sure this is the CDS mix? I've read around and it has been claimed to be it but I was under the impression it would use the same sound effects from the official theatrical trailer:

I know it's just a compressed mp3 for YouTube but there is something about the sound in that trailer that feels more dynamic and explosive even if it may not be natural or full of fidelity. The audio for that trailer very well could have just been made specifically for a promo but I like to believe the real CDS mix would sound like that. Listen to the shotgun blasts, the explosions, and especially the shots fired by the T-1000 at 1:36 - they sound like they have more punch than what is in the actual Live DVD or any other release.
On a side note, I noticed there are 2 versions of the '98 R1 DVD - a snapcase with LIVE on the side bottom and lower right bottom of the front and a plastic standard DVD case with ARTISAN in place. Both come with the exact same disc catalog # 60441. I wasn't sure if maybe one release may have been different than the other but it turns out the only difference is the case.
Also, here is a fun read regarding the sound design of the film:
