Things aren't RECORDED in DTS or DD. Those are compression/expansion systems designed for PLAYBACK, just as Dolby-B and -C are 'compansion' systems for analog tape. Most motion pictures are recorded in CD resolution, 44.1KHz/16bit, and DTS and DD do indeed use '44/16' for playback.
The originals are/were recorded with whatever is/was current and available. The Al Dimeola probably wasn't recorded in 2-track; I expect a MANY-track recorder was used. The quality of the current 6-channel audio track is related DIRECTLY to the quality of the masters AND the attitudes and skills of the rerelease producer--some stink, some don't. This is true for 2- and multitrack DVD-As, too. SOME of the best I have were recorded in 4- or 5-track analog 30 to almost-50 years ago. I also have some GREAT-sounding DVD-As recorded recently in 96/24.
One thing I continue to be disappointed in regarding multitrack music is the high noise levels of SACDs, and those that were mastered in DSD are some of the noisiest. That's why I prefer DVD-As, and I'm VERY glad both of the hi-def-DVD formats will be using PCM encoding and not DSD.
BTW the only significant difference between DTS and DD is the amount of compression each uses. DD uses much more compression, with the maximum transfer rate of DTS about 5 times that of DD; that's one reason a DTS audio track almost always sounds better than a DD audio track.
