It's probably easier to fix one's pet even if one is not a vet, but here goes anyway...
Generally, the way the lead vocals seem to float in space towards the left drives me totally bananas...and they ain't the Snood good kind of bananas. So most of what I did focused on getting the lead vocals more centered.
Wouldn't It Be Nice
To me, this is the most screwed up song of the lot possibly having swapped tracks as others have noted, along with anemic bass and floating lead vocals.
Here is a visual of cut 1 (unaltered) from the 5.1 of the DVD-A:
So I did the bulk of the work on Wouldn't It Be Nice to get something I finally liked.
Track 1 (Left Front)
Source: 5.1 DVD-A Left Front Channel
Adjustment: Reduce volume -2 dB
Track 2 (Right Front)
Source: 5.1 DVD-A Right Front Channel
Adjustment: None
Track 3 (Center)
Source: 5.1 DVD-A Center
Adjustment: DVD-A authored incorrectly. Swap with LFE.
Track 4 (LFE)
Source: 5.1 DVD-A LFE
Adjustment:
DVD-A authored incorrectly. Swap with Center.
Boost significantly (as high as possible without clipping) to add bass to final product.
(Adjust boost to taste.)
Track 5 (Left Surround)
Source: Stereo DVD-A without lead vocals
Adjustments:
Reduce volume -5dB
Mute drum sticks at beginning
Time align with Left Front
Track 6 (Right Surround)
Source: Stereo DVD-A without lead vocals
Adjustments:
Reduce volume -5dB
Mute drum sticks at beginning
Time align with Right Front
Here is a visual of the stereo tracks from "cut" 15 of the stereo layer of the DVD-A that becomes the new surrounds on the remixed 5.1:
Here is what the new version of Wouldn't It Be Nice looks like:
And here's what I eventually settled on for the rest of the tracks:
Most of the modifications simply involved reducing the volume of the Left Front channel to help get the lead vocal centered. I tried other manipulations, but none of them worked for me. For example, listening to Sloop John B track by track, I got the impression that the channels were completely convoluted and tried all sorts of reassignments. Doing so resulted in a mix with dead center lead vocals but terribly anemic surround sound. So I stayed with the original mix and simply lowered the front left by -2 dB.
On I'm Waiting For The Day, the surrounds are a bit overwhelming. Dropping the level of the surrounds by -2 dB and well as lowering the LF -2 dB is my preference.
Perhaps the most remarkable adjustment was the -4 dB LF reduction on I Know There's An Answer. Looking at the stream in Audacity gives the impression that - 4 dB is way too much, but it sounds right for whatever reason.
Listening to these songs over and over actually made me realize the greatness of Pet Sounds. I never owned it prior to getting the DVD-A; and I had never played it through because I couldn't deal with the problematic mix.
Let me know what you think and if you have any suggestions.
