-------------------------------------------------------------------------------- Tell me if I'm wrong but to get true 5.1 DTS wouldn't the songs of had to have been recorded for this purpose anyway? Or at least the original master tapes would have to be accessed and re-mixed for 5.1. Surely EMI are not going to let the master tapes go out to another company for this purpose or any purpose. I doubt very much if this is genuine 5.1 DTS
Sounds interesting Blue Meanie. I will have to get hold of a copy. However, it is only pseudo 5.1 after all. The best vinyl copy will proabably be a stereo album and that gives them 2 tracks to manipulate into 5.1. I don't think it should be marketed as though it was true 5.1 though because they don't have the masters. Still, I will check it out. Thanks.

TOUP have been doing amazing things in 5.1 for a few years. Not just with The Beatles, but also The Stones, Zappa, and Jethro Tull, to name a few. Their starting point is the best possible vinyl copy available, and take it from there. You can do incredible things with software these days, allowing you to eliminate channels, therefore allowing you to construct a faux multi-channel 'master'. Of course it's never going to be as good as having the original, but you'd be amazed at how good some of this stuff sounds.

Consider a few things:
5.1 means 5 channels of POSSIBLE sound, plus one of subwoofer. When doing 5.1 mixing, adding some bass from the other parts into a subwoofer channel is easy. So - the rest is what you're asking about...
When you mix a tape into 5.1, you take the sounds and pan (or assign) them to various speakers (two front L/R, two rear L/R and one middle). You can pan ONE track right between the front and back LEFT speakers, and could pan another one between the front and back RIGHT speakers. So - you're already using four of the channels with only two tracks. If you put one vocal in the center, maybe add some reverb or echo to any other channel - you're making a nice 5.1 mix.
So - the Beatles early music can use only two channels of source (music and vocals). But they can also add some reverb, or just leave it as two parts. Anything later than 1964 is usually four or eight tracks of music and voices; easily spread around 5.1 systems.
As you know, the old 4 track machines only records four channels - but they also filled up one machine and added more tracks on another tape - by "bouncing" things to another machine with mixing being done - so 4 tracks got "reduced" into only one or two on the new machine. WIth computer audio, you can now go back to the early set of four tracks and keep the separate and then add in all the later tracks - also separate. Then you have LOTS of tracks to work with and pan/effect as you like it.
What lots of these people are doing (bootleggers) is make a regular CD of the single 5.1 channels - so you can hear JUST the bass, or JUST the vocal track. Interesting stuff....! I think these may be either the single tracks brought out, or someone making a "fake" 5.1 from isolated tracks...

Another old trick from the '70s (if you had 2 channel stereo, not quad) was to take a third speaker and hook it up to the positive leads of both channels. In other words, hook up the left positive lead to the third speaker's positive input, hook up the right positive lead to the third speaker's negative input, and you could get a third channel made up of sounds that had been cancelled out in the stereo mixdown. Of course, this varied, depending on how much stuff had been cancelled out.
Records like the first McCartney album of anything else done as a one-man band didn't have much of a third channel, but if there were numerous instruments playing at one time (as in a live performance) you could get some stuff you didn't hear before.
I'm no technician, but if that can be done of the line level instead of the speaker level, it shouldn't be too hard to get extra channels from stereo. Of course, the two rear speakers will be identical.

I think that is what's now commonly known as an OOPSing effect (Out Of Phase Speakers) - basically, what that does is cancel out everything recorded centrally in a stereo mix (commonly vocals, bass and drums) leaving everything recorded left and right of centre still audible - not very effective on The Beatles' early recordings though!
A really effective example can be found when OOPSing Ob-la-di Ob-la-da - all the music disappears leaving only the vocal track - this is possible because the backing is mixed in mono with the vocals mixed with a slight delay between the left and and right channels.
And yeah, it most definitely is possible to replicate this 3 channel method effect via line inputs. Probably need two amps though(?).
