Hopefully this means the riffers are somewhat louder relative to the movie audio, compared to the previous version.
Whatever it means though, is there any chance the new mix will be reuploaded to either the download to burn or the VoD files. I've already paid for both of these, and as much as I like this riff, there's simply no way I'm buying it a third time.
You pretty much nailed it - there's also less compression and noise reduction artifacts in the source. I will, as time permits, be replacing the other VOD files with the new audio version.
So I was just wondering recently, has this been done yet? I just wanted to know it it would be worth my while to redownload the D2B at this point.
