Not sure where to post this but I have on my computer a Dolby Digital trailer (that starts with some drops over a liquid surface to let the words Dolby Digital to appear briefly to left again the liquid surface) and a dts trailer (shows the strings of a piano from inside the instrument while starting to being played, but just a few notes) on *.vob format.

I believe I took those from the Der Untergang (The Downfall, see the trailer on ML FE) movie DVD.

Dolby Digital *.vob trailer - 5 MB

dts *.vob trailer - 10 MB
