DTS HD Master & Dolby True HD set up


Hi everybody.
I have denon 2500btci blu-ray support DTS HD Master & Dolby true HD and use denon avr4306 for pre/pro.
If I want to enjoy this new HD format which should I choose.
setup blu-ray has
*Mix Audio Output-Output the secondary and interactive audio with primary audio if it is available(audio will be output in a multi LPCM format.)
*HD Audio Output-Output only the primary audio(audio will be output in bitstream.)
Which one should I choose.
2nd question is
*HDMI Multi(normal)-The multi-channel audio signals are output from the HDMI OUT with bitstream or LPCM
*HDMI Multi(LPCM)-The multi-channel audio signals are
output from the HDMI OUT with a LPCM.
which one should I choose for ..new HD format.
Need your help....Thanks

Hi everyone.
I just got e-mail from Paul Belanger Denon Canada.
He said
Denon DVD2500 & DVD1800btci Both only support DTS HD & Dolby Tru HD via bitstream to an HDMI 1.3 enabled AVR.
With means looks like I needs new receiver such as Denon AVR3808ci or Integra DHC9.9 for pre/pro.
I know nothing about Integra.
Whichone should I choose.
needs your help.
thanks

Because the 2500 was originally marketed as a transport to connect to processors that could decode the HD codecs and to differentiate it from the 3800.

Funny, it seems even Denon themselves don't know what this thing will output!
