Early LD AC-3 tracks used the original film mixes, but The Matrix came much later and was one of the gateway titles for the new DVD format. Would they have prepared two separate AC-3 tracks for the two platforms when they were being released almost simultaneously? If a home video 5.1 mix was made, would it not have made sense to use it for both (meaning that the LD AC-3 track would be the same as the DVD's except for the bit rate). I could (and hope that I am) wrong.

I'm just asking questions here; I don't know. I've never heard the LD AC-3 track for The Matrix, and wouldn't know how it compares to the DVD.

I was also wondering if the LDs PCM track was just a folddown of the 5.1 track or was it it's own mix?

And was the theatrical Dolby Digital mix different from the DTS mix (which I've heard and is a lot of fun)?
