The reason I wonder about this is that there are very few (relative to total numbers, 13,000 or so) DVDs out there with DTS. I would have figured at least 10% of pre-existing DVDs would have to have DTS sound for it to be considered a success. I think the number is closer to 1.5% right now. I don't know the number of DTS Cds though. Has Universal released all their films in DTS?
