Aldo, first of all, digital mixes may very well have NO surround information (check out Woody Allen's latest films). For one thing, Dolby A optic stereo prints are matrixed, digital formats today are discrete. Optic stereo surrounds won't be as clean sounding (there is leakage from the front). Scratches can cause sound problems. High frequencies don't phase as well as other frequencies, so those sounds (the clicks of a door, the clanging of keys) tend to also get into the surrounds (a reason why Allen now uses DIG, because pleas to projectionists to kill their surrounds for his movies have gone unheeded in every showing i've seen of his). So an extra surround "ambience" is created through this matrix. And of course, no splits are involved. Obviously, a matrixed track reveals how well sound heads are aligned (which is why EX decoding works so well, since the soundtrack is digital and if tracking correctly, the balance necessary for redeveloping the back center channel is dead-on accurate).
i've heard a number of films play back where the DIG drops out for a reel and the sound almost has a "spitting" nature to it, and holding dialogue to the center speaker doesn't always hold. Of course, the American Cinemateche, as Mike Coate attested to, has superior operators who really care about film presentation, so you can guarantee they keep everything aligned properly, since they will have fewer shows in discrete digital than in other formats.
Of course, 70mm mag prints, if properly used, will sound (arguably) as good as digital prints, and many will say SR-encoded magprints will sound even better. I was mainly pointing out some differences between Dolby A analog (stereo optic only, Dolby encoded mag prints did exist) and Dolby Digital for 35mm film presentations.
