i was just wondering why they would bother taking up additional disc space with a DD 2.0 track on a DTS dvd? this DTS disc was only $9 new at best buy, but i have to say so far i would say it's not worth much more than that because the video quality is seriously lacking. plus, it's the first dvd with a dts track i've tested on my upstairs system that has some serious distortion in the heavy bass sections. anyone else have that problem? maybe my in-ceiling sonance subs can't handle this particular track.... although i've fed them some serious bass before with no problems.
