First of all, I just came across these terms only briefly, and I may have misinterpreted them. But are there DTS tracks that are recorded not in their full glory? I mean, do studio compress DTS more than usual to make room for other stuff (a DD5.1 track, uncompromised video - see MIB)? How do we know which DTS tracks are recorded at 1.2Mbps (correct?) and which are not? Thanks.
