So... I have an HD DVD player connected to a Pioneer Elite VSX-80TXV receiver. The HD DVD player connects via component and optical for video and audio respectively.
My question is... what is the difference between connecting audio via
vs 2. HDMI to receiver with no TrueHD support
vs 3. HDMI to receiver with TrueHD support
Should I keep what I have? upgrade to the 81TXV? or should I go with VSX-91TXH?
I see your AVR has HDMI. Why are you using component and optical from your HDDVD? What HDDVD player do you have? I will guess your tv doesnt have HDMI?
Opticals max is DD and DTS also Coax.
HDMI will do TrueHD DTShd. But PS3 will convert it to PCM which most all AVR will handle which is the same. My HDDVD to my Onkyo 804 TrueHD is displayed as PCM the only format available to me that way on my AVR. Some other AVR's can add in DPLII to take advantage of 7.1 channels. TrueHD DTSHD currently only support 5.1 as far as I know right now. I also have mine connected analog 5.1 which also passes TrueHD which is multichannel inputs. Thats right you heard me analog. This is where sony fails on most of there BR devices. The PS3 doesn't have these.
As far as a TrueHD capable receiver connected to HDDVD & PS3 HDMI from what I know its still receiving PCM from the PS3 and HDDVD because they are unable to pass these formats. They are converted to PCM. Then this is sent to the AVR your AVR will probably still display to you its PCM. This what you want its DTrueHD.
I hope this helps explain this. If I'm not correct someone please correct me.
One note. I see this question here allot.
If you want to experience these new audio formats.
You have to connect the source to the AVR then out to TV for video.
Your TV cannot do pass through these formats. Usually the audio out is coax, this does not support these formats. Unless it has an HDMI out.
