Greve : as long as your CD player has a digital output you will be OK. I have a Yamaha 110 disk CD chanter with an optical output and it woks just fine. You can even copy DTS CDs just as you would a normal CD. The DTS CDs use the same header format as a standard CD and the bit stream is just passed from your CD player to your receiver. Your CD player just thinks that it is playing a normal CD.
I think that there was a thread here about someone not being able to play DTS CDs in a DVD player with built in decoders because the DVD player was fooled into thinking that it was just a CD and put out only two channels of garbage.
The best place I have found for DTS CDs is here

Word of warning once you listen to the sound of a DTS CD you will be disappointed with standard CDs.

Hi Roger,
I've copied this easy to remember url -

which is obviously a biased view, but there you go. I've also noticed that DTS soundtracks appear to 'come alive' more in some movies. Enemy at The Gates is but one example.

I think what Dolby are saying is that their system filters out sounds which the technology has decided we cannot detect with our humble ears. I think their are also other issues here, because in the US films tend to have more special features (apparently due to niggles over whether supplemental material not part of the released movie is covered for export in terms of loyalties/export licensing etc) than here in the UK, US films also manage to ship with DTS far more often as well. If they can fit BOTH onto a region 1 DVD, and do half a job on the R2 version, 'lack of disc space' appears to be a slightly lame excuse.

I too have a dd and dts which is also dts es and dd ex I spent hour switching between the two formats and completly agree with rick, spatial, it widens the sound field without making it false and is clearer, but, it took me over an hour to find this out, so does it really matter!

Now, the real difference is between dd ex and dts es, there i think there is a huge gap but unfortunately not enough discs to satisfy me. The two big films for this are i think 'Gladiator' region one and 'Terminator 2' Region two. Gladiator especially gets my juices flowing.
