Pretty sure it's DVD-V with DTS audio for the 5.1. I know Rob would have preferred loss-less but it's the age old problem of balancing his desire to get it out in 5.1 in a commercially viable way. Besides, I'm not that bothered as Rob has a well proven track record of making DTS sound way better than it has any right to.
Ok, well I'll wait until people receive their copies and can confirm what kind of DVD it is before I hit the order button myself. Not sure if $28 is a worthwhile price to me for a DVD-V disc of unfamiliar music.
