Super Speedway Mach II DTS ?

[mhw58]

A recent thread recommended 'Super Speedway' as a
great dvd. I bought the Mach II version which says it
is DTS on the box. I played the dvd last night but there
is no DTS option for the sound, just Dolby Digital.
The DD sounds great but I'm wondering why there is
no DTS when the box says it is DTS. Am I missing something?
Does anyone have this version and is yours DTS?
Thanks, Mike

I do not have the DTS version but from what I have read DTS comes up when you switch the aspect ratio to 16:9

Thanks for the info and you're right. I watched the dvd last night
and when you set the video to 16x9, the dts option is there.
On 4x3, it's just dd.
