Guys;\n\nI've heard from a very good source today that the next generation AV receivers and processors will no longer allow non-native upmixing of mult-ch content. In other words, if your source is encoded in DTS HD, Dolby won't allow you to use the DSU. Instead you will have to use the DTS:X upmixer. Similarly if you have a Dolby TrueHD source, you can't use the DTS or Auro upmixers. This is something that has always been in the guidelines for all of the CODEC's but never enforced. I believe Dolby may enforce it for 2 reasons:\n1. Control quality of content so that their upmixer is only used with their software\n2. Put an end to Auro 3D.\n\nLet's face it, Auro 3D is practically giving their licensing for free to Denon and Marantz to stay alive in the consumer marketplace.\n\nAnybody have further info about this? MCODE anything to add\/confirm in this rumor mill rant I just made?
