which track goes with which... track?
I recently discovered the glory of the foobar2000 DVD-A component, not coincidentally as I was discovering the glory of King Crimson. I've now got all but two of the 40th Anniversary Series CD+DVD-A releases. I have no problem playing or converting to FLAC the stereo versions of the DVD-A MLP tracks, but several of the albums have both the Steve Wilson remixes and the earlier 30th anniversary remasters in 24/96 MLP.
The problem is determining which tracks, as presented by loading the IFO file in foobar, are which. I've had an email exchange with Neil Wilkes, who works for Opus Productions, and authored most of the DVDs in the 40th Anniversary Series (In The Court Of The Crimson King being one exception, though he is credited on that release). He claims that it's not possible to tell how the foobar component displays the contents in relation to how the DVD was authored. Thus, he would not give a definitive answer. As he's the author, I can only take him at his word.
Without getting into too much detail about the back-and-forth, these are the two relevant replies from Neil re: Starless And Bible Black:
"The 2 40th anniversary streams (stereo & surround) are in the same VOB in the Video_TS and the same AOB in the Audio_TS."
"Sticking strictly to the Audio_TS, it was set up like this:
Group 1 = 40th Anniversary Steven Wilson remixes.
Content set as both surround & stereo in the same group - this is known as "PGC Blovk" [sic: presumably he meant "PGC Block"] authoring, and is done to make the disc work 100% by simply loading the disc, waiting for the main menu to load & hitting PLAY or ENTER to get straight to the new content in the stream setup your player is configured for - The 5.1 is stream 1 and the 2.0 is stream 2 ( or stream 0 & stream 1, depending on how the player displays the information)
Group 2 is the 30th anniversary stereo mix at 24/96 in MLP Lossless
All other content is in Video_TS only."
That's all well and good, but doesn't help those of us without DVD-Audio players. Perhaps the component creator or someone more knowledgeable than I can weigh in.
At this point I'm reduced to listening to the two versions of a given song, trying to find differences in the mixes, and then comparing that section to either the 30th or 40th anniversary CD versions. That's the theory, at least. As you might imagine, that's a tedious task, and not one I've yet had the time to tackle.
As I'm still researching this, perhaps there is some freeware DVD-A ripping app I've not come across that can deal with the .AOB files directly. I'm going to assume Neil's explanation of the remixes being loaded first applies to all the DVDs. I don't like assumptions, though.
