BD doesn't really have any required audio track. It can be any of the following or any combination of them:
1. LPCM uncompressed tracks.
2. Dolby TureHD and/or Dolby Digital. If a disc contains TrueHD, a DD companion track is required for compatibility.
3. DTS or DTS-HD. If a disc contains DTS-HD, a DTS core is already part of it. So, no separate DTS track required.
#1 happens mainly on early releases during format wars. #3 currently is the most popular choice.












Next thing you know, they'll start sticking Blu Ray's in the DVD version so that way they think they'll get more people to buy BR players, so that in turn will boost BR sales down the road.
