The DTS would have less compression, if I’m not mistaken.
Yes and no. The theatrical DTS algorithm (APT X100) has nothing to do with the home DTS. It is actually compressed at 882 kbps with 4:1 ratio, on 5.0 tracks (the LFE is encoded with the surround channels).
On the other hand, the Laserdisc Dolby-AC3 is encoded at 384 kbps, but with a totally different algorithm than DTS APT-X100, and real 5.1 tracks (or 6.1, if I’m not mistaken, on the Laserdisc of TPM).
So basically, it is difficult to compare both formats.
And again, to me it’s preferable for consistency with Schorman’s theatrical ROTS and the fact that pretty much every theatrical restoration for which cinema DTS is available uses that track as the primary.
I agree, I was just talking about the argument “DTS is the original cinema format”. But yes, it seems more logical and consistent with other projects to make DTS the default track.
