Very interesting! Does it seem like they're really meant to be the same track but one has technical limitations?
I ask because the text on the original US DVD was always a bit ambiguous to me as far as how truly accurate the 5.0 version is.
they appear to be the same but the DVD has QS decoded Rears which definitely have some technical drawbacks, while the Blu-ray is totally discrete, the DVD tracks good but the Blu-ray is amazing!!
