hi,well still i a very confused with this matter,i have a blu ray and hd dvd version's of 300.
i use a playstation 3 like blu ray player and a the toshiba xa2 like hd dvd player.

1-i set both versions in true dolby hd
2-i use the exact settings in my onkyo 805.

note:when i set the 805 in the playstation 3 line,the lcd panel in the 805 show the word"multichannel"for default,and the speakers lights on and off when the blue ray start booting,that not happen with the hd dvd movies.

the blu ray version have a really bigger and more powerful sound than the hd dvd version!!!!even that both versions are played in dolby true hd!!!!
i sell my xbox 360 hd dvd player and buy the xa2 for that issue!!!!!

i notice that all the blu ray movies sound more better in terms of power and volume than the hd dvd ones...............

my question still is the same:is a problem with the hd dvd movies??problem with the x2a???problem with mt 805??(i dont think my 805,blu ray sounds awesome!!)

i really love both formats,but i a big sound fan too,so right now i worried for that issue with the hd dvd movies.

any ideas???

thanks

I think its well known that the PS3 gives out the stream at a louder volume. Just increase your volume level. Yes, they are both TruHD, but the HDDVD usually brings down the volume so that they can mix in a secondary stream, and the player "beeps" if you have them on.

When comparing two sounds, people always say the louder one sounds better. You have to match the volume level to within 0.5dB to make any meaningful comparisons of sound quality. If you then hear a difference, perhaps there is something happening in your setup.

thanks for the answer,well not just the ps3 sounds louder,i give you a clear example.

in the blu ray version of 300, in the beginning of the movie,when the warner bros logo appear,using -20db volumen,all my living room shaking!!!!
that not happen in the hd dvd version,as i say before,i use the same setthings in my onkyo 805 and both players in dolby true hd,so the blu ray version not just sounds louder,sounds with a really big output power too.

thanks!!!

note:the toshiba x2a dont need any special settings??

TrueHD is a really crappy excuse for lossless track. We should really demand DTS-MA on both formats. TrueHD is a cop out IMO.

are you sure your xa2 is set up correctly? hard to imagine the truehd on blu-ray would sound better than the truehd on hd dvd. the pcm sounds better minus dialog normalization, but the truehd tracks should sound the same. how are your 2 players connected, both via hdmi?

another thing to try is switch the inputs, plug your ps3 to where you have the xa2 and vice versa. see if the issue persists.

If your receiver said "multichannel" then it is not seeing Dolby True HD, it received PCM, you must have select 5.1 uncompressed PCM instead.
I forgot, if under BD audio output settings HDMI and you chose linear PCM, then the PS3 will decode Dolby TrueHD and send it out as PCM, that is why your receiver said multichannel, if you set it to bitstream, then your receiver will said True HD.

to OP, your receiver will not say TrueHD/DTS-MA unless you have a player with HDMI 1.3 capable of bitstreaming the audio to the receiver for decoding.

True, but its still outputting TrueHD. It's just doesn't tell you that because it doesn't "know".

Isn't that assuming you use analog outputs from your player (which the ps3 doesn't have)? I thought the ps3 could not bitstream the advanced codecs yet...

Correct.

The reason why he has different volume level is because in the case of PS3, the player is doing the decoding and sending out Multichannel PCM via HDMI. XA2 is outputting raw bitstream and the receiver is decoding the TrueHD. The volume difference could also come from how much volume (voltage) adjustment is made by the receiver with PCM input from PS3.

IIRC, the XA2 still can't output TrueHd via bitstream. I have one and I'm still waiting for a firmware update to allow it. The only option right now is to allow the player to decode it and output it as PCM to your receiver.

I just checked, if you go into the PS3 menu/BD audio output HDMI and set it to bitstream instead of Linear PCM, the receiver will light up Dolby THD, if you set it to Linear PCM, then the receiver will light up multichannel PCM.

can XA2 output TrueHD via bitstream? i didnt think it had HDMI 1.3.

It definitely have HDMI 1.3, but cannot (yet) output bitstream HBR (High Bit Rate) and same for PS3...

They both decode DTHD and output as PCM over HDMI... Setup both players, then correct your level (you have to up it up when using XA2) and then compare you should have exact same results... At least I have here...

Can someone else confirm ps3 passes TrueHD bitstream? Was this just in a recent firmware update?

The PS3 does not pass TrueHD via bitstream.

On my system the PS3 is also louder than my HD DVD player and my Sat. receiver. doesn't mean it's better, just louder.

Perhaps you have the volume level in the PS3 set quite a bit higher? It's located in the PS3 and can be adjusted by using the options menu.

Sorry about that, it says Dolby D, I took a quick glance and thought that it was Dolby True HD, it display was so small on my receiver, my bad.
