It doesn't, but again, when people complain about a game being 3 to 5 discs, a 4th or 5th disc for DD 5.1 wouldn't sit too well, now would it? The DVD-ROM would only serve as a technology enabler, as 9GB on a single disc compard to ~800MB allows for significantly more data storage.
Can't it just be encoded on the fly from within whatever application is outputting the sound? Surely, you don't think that all of your X-Box sound is just pre-recorded sound clips playing off of the DVD?
Sure, it can be encoded on the fly, but it will still only sound as good as the original stream. 5.1 encoded sound ALWAYS sounds better than real-time DD encoded from a 2.0/2.1 source (which is what you get in most PC games). Also, you'd need hardware capable of real-time DD encoding/upmixing (nForce, XBox), and it still won't sound as good as DD 5.1 that is simply passed through to a DD decoder. Positional sound is much better, and again, so is the LFE (being on a discrete channel rather than crossing over from 2.0). If anything, a pre-encoded AC-3 stream will take up less space than a true 5.1 track, which needs to be encoded and then decoded. And no, my XBox isn't playing pre-recorded sound clips, but it does use pre-encoded AC-3 streams for its DD and isn't simply encoding standard 2.0 stereo.
As far as the abuse of full motion video...a LOT of FMV sequences were implemented in terrible and unavoidable (to the gamer) ways. We would have gotten away easy if it was just used for cut-scenes back then!
Imagine playing a jet-fighter type of game where the programmers decided to interrupt your gameplay with a FMV sequence of a launching missile every time you launched one. Or, how about a driving game where the track is pre-recorded full-screen video of a "real" race track with your video-game car just superimposed on the video?
I don't think you'd like either of those.
You're right, I wouldn't like it, but then again, I wouldn't buy it (and didn't, since we are speaking historically). I'm still not sure what games you're referring to, maybe I got lucky and avoided all the crappy games that abused FMV? Or maybe I did my homework and didn't buy cheesy games in that genre to begin with.
