Theres been a lot of talk on this subject at other sites...speculating that the Toshibas will not do even 5.1 DTS-HD...despite the way they advertise the specs. In S&V, the Toshiba advertisement has fine print that states..DTS-HD supports up to 5.1 channels of DTS core only. This would mean either regular DTS or double bit rate...and no lossless. Someone on a different forum, claims they called DTS, and indeed the Toshibas will not do lossless Dts...according to the poster. It may not matter much because there are no 7.1 soundtracks yet, and probably will not be many, if any, anytime soon....but has anyone here actually talked to somebody at DTS, to get to the bottom of all of this?
