Here's my setup:

Harmon Kardon AVR-140 Reciever, Toshiba HD-D3 Player, Panasonic TH50PZ77 50" Plasma

HD-DVD hooked to TV via HDMI.
TV audio hooked to Receiver via Optical Cable.

Whenever I play movies using the D3 player, I cannot get my receiver to select "Dolby Digital" for the true 5.1 sound; only ProLogic, Logic7, etc.

However, when I play disks in my LG DVD Player (DivX, home movies, etc), connected via Coaxial cable to the Reciever, "Dolby Digital" plays just fine.

I'm assuming I have to tweak the menu (audio) options with the HD Toshiba player or hook it up different, but I'm not sure which steps I should take.

Any advice?

Here's my complete setup if necessary:
Harmon Kardon AVR-140 Reciever
Toshiba HD-D3 Player
Panasonic TH50PZ77 50" Plasma
LG DivX DVD Player
XBox 360
PVR

HD-DVD hooked to TV via HDMI.
PVR hooked to TV via HDMI.
TV AUDIO OUT audio hooked to Receiver via Optical Cable.
LG DVD hooked to TV via Component Cable and and hooked to receiver via Coaxial Cable. Dolby Digital plays fine here, but not with the Toshiba HD Player.

Sounds like the TV is downmixing the audio signal to stereo and the receiver is only having that to work with. Most TVs with a digital out only put out 5.1 signals for their internal tuners, and any other audio signal they get is downmixed. Not sure about your model but I'd say it's a safe bet that this is what's happening.

Your DVD player is putting out Dolby Digital as it is hooked in directly. Try connecting the HD-DVD player direct to the receiver.

Ok, hooked the HD player directly into the receiver via Optical and same problem. Can't get anything higher than "Dolby PL".

Oh, and I upgraded the firmware on the DVD player as well (hoping that might be the problem).

The Audio Settings on the HD Player Menu are (* - currently selected):

1) Digital Out SPDIF
Bitstream
* PCM

2) Digital Out HDMI
Auto
* PCM
Downmixed PCM

3) Dynamic Range Control
* Auto
On
Off

4) Dialog Enhancement
On
* Off

Just did a search of these options and found "PCM will not send Dolby Digital or DTS to the receiver even if the DVD player is compatible with those audio formats". I think that answers my problems, brb

Shouldn't that be set to Bitstream when using SPDIF?

When SPDIF=PCM, legacy DD and DTS are also decoded in the player and sent to the receiver as PCM. It should be fine, although it may make more sense to do the legacy decoding in the receiver. At any rate, if you leave this setting as PCM, you won't see DD or DTS in the receiver display.

There's a note in the A3 manual about the HDMI setting when using SPDIF. It says the SPDIF output level may be lowered when HDMI=Auto or PCM and your player is connected directly to a TV using HDMI. So, you may want to put that setting at Downmixed PCM to assure proper volume.

Here's my setup:

Harmon Kardon AVR-247 Reciever, Toshiba HD-D3 Player, Panasonic TH50PZ77 50" Plasma.

The problem is that I am not getting any dialog sound, even after I updated the firmware. The HD player is conected to the receiver via HDMI. Digital Out HDMI is set to auto.

Is there a setting in this player that I am missing that would help me solve this problem?
