Dude, you probably bought the wrong DVD player! Here's hoping you have one
that supports DVD-Audio.
I have one that doesn't support DVD-Audio, and an older LaserDisc plus DVD
combo-player that doesn't support DTS -or- DVD-Audio. Looks like I need a
third DVD player (unless one of these Macs can handle DVD-Audio...) Both DVD
players are compatible with DTS music disks (up to 5.1 channel music), but only
the new one can handle DTS movies - go figure...

Bjork - Vespertine (DVD-Audio) is listed on Pre-Order @ DVD Planet
I've met a few electronic artists who perform live with a surround system (4
or more channels), and I've been trying to convince them to record and release
multi-channel DTS audio. I suppose DVD-Audio would be a good choice, too, but
I selfishly want something that will work on my CD players instead of requiring
a new DVD player.

DVD actually stands for Digital Versatile Disc, so it isn't just for video.
I agree, though, with the statement that anyone I like probably won't be
putting out anything on these new formats (with the exception of Bjork above,
and anybody we can convince).

Uh, these things are all or nothing. If your deck doesn't handle 90+ CDRs,
then you won't get anything! Unless these discs are physically larger in
diameter (I haven't seen one, but I doubt they changed the size), then they get
the extra 10 to 19 minutes by squeezing the track spiral tighter. Kinda like
those low-dynamic-range vinyl discs that get 30 minutes per side (only CD
doesn't lose dynamic range, it simply stops working on decks that don't expect
the change).
It's not as if the new 90+ discs are exactly the same out to the 80 minute
mark and then suddenly they add 20 minutes - nope, the only way to do that
would be to make a larger disc (which would be a third size, given the existing
24 minute and 79:59 formats). The 80 minute discs were already using all the
space on the platter, so 99 minute discs are just wound tighter - with closer
track spacings - and cover the same area on the platter.
[ i don't even know if these work in normal cd drives.
They might, but it will probably be rare.
The original 74 minute blanks aren't "correct" according to the CD-Audio
specification, because the track spiral is spread out a little more to allow
the burner more space to work in. Older players don't expect the extra space
between each loop of the spiral, so they won't play CDR. Newer players can
handle a variety of track spacings, but who knows if they'll adjust to the
tighter winding in the 90/99 minute blanks!
