The difference on the DVD for Dolby Digital versus two channel PCM:
Stereo 320-kbps Dolby Digital for 92 minutes = 176mbits = 22MB
Stereo 48/16 PCM stereo for 92 minutes = 8478.7mbps = 1059MB (makes sense since a CD is 700MB and that would be 70 minutes at 44.1/16)
So over a gigbyte difference on an 8.5GB disc. That's 12.4% of the total disc.
What would you like to give up on the disc for a PCM track?
It actually costs more money to include Dolby Digital since there are licensing fees (relatively small) with Dolby Digital that you don't have to include with PCM.
While it may provide more incentive to purchase the BD as well, the real reason for not including PCM is the small size of a DVD disc.
