What happens if I play a DTS-HD track on a player that does not have support for DTS-HD decoding?
DTS-HD decoding is optional and currently no HD DVD player has support for internal DTS-HD decoder. If a capable player is in bitstream mode it can bitstream the DTS-HD track to a compatible receiver. All other players will extract the lossy DTS “core” from the track. The core is a 5.1 DTS track encoded @ 1.5Mbps.
