You could ask Rozard.
Soul Cleansing looks awesome, and that's definitely from the DVDs (an idea backed up by the 'Remastered' in the filename, but I'm not saying anymore).
Aside from that, I don't know what the DVDs look like, but if it's anything like the R2 of End Of Eva Renewal, light smoothing should be all that it needs (and I only say that because a light smoothing almost never hurts). Just check to see if it's mostly Film or has a 3:2 pulldown flag and set DGIndex accordingly during that step - but as you're working on the scripts themselves I assume you've already done that).
