I have experianced it with DVD, there are only a few select titles that featured D-Box compatitability and you had to order them special (you couldn't just go to Best Buy and pick one up). But it sounds like Blu-ray is just throwing it on their discs as an extra feature. The chairs are very expensive. The systems can range from at the lowest (this is from memory) $5000, if even that low, to $20,000. It is entertaining to say the least, but if your pockets are lined with anything short of Gold you may not find it worthy of purchase.
