No, this is not true, DVD-A is not the same thing as dts. However,
just about all commercial dvd-a discs do contain a dvd-v portion which
contains the album in dolby digital, so a surround player for the car
that can play dolby digital from a dvd will play that off the dvd-a,
and probably be good enough for the car. Many dvd-a discs do contain
dts on the dvd-v portion of the disc, but not all. However, if you
have a dvd-a discs that has no dvd-v portion, like some of my earlier
conversions, you won't be able to play those in the car on this
player.
