Dts Hd-ma
Clint mentions support for:
"... Dolby TrueHD, Dolby Digital Plus, DTS-HD Master Audio ... "
but Onkyo's own press release says:
"... including internal decoding for DTS-HD, Dolby TrueHD and Dolby Digital Plus."
The TX-SR605 press release goes further:
"It is among the first receivers available to include decoding for Dolby Digital Plus, Dolby TrueHD, and DTS-HD Master multichannel audio formats from Blu-Ray and HD-DVD players."
If it only does DTS HD, any DTS HD-MA titles will only decode as core DTS.
