Wow, I really screwed up, didn't I? I guess I meant to say, it's the only version that's *not compressed to 192kbps.*
Another thing which needs to be captured is a PCM mono track from an LD of The Wizard of Oz (perhaps the "Ultimate Oz" box set?). All DVD/Blu-ray releases from 1999 onward have a weird error in the parlor scene in Kansas; before '99, Dorothy said "Oh, Toto, don't..." but in all the DVD/Blu-ray releases except for the original MGM one, it cuts off mid-sentence. Even the "restored" mono track on the more recent releases has this problem.
Again, the original MGM DVD has the mono track as it used to sound, but it's compressed Dolby Digital. An uncompressed version can only be found on laserdisc.
