So yeah, just to get it out there, the player software decodes the codec, then re-encodes to something the system can output do to hardware limitations. The Major Nelson HD-DVD feature that was all about the Add-On even mentioned that the hardest thing they accomplished was the decoding of TrueHD on the drive. It is a REQUIRMENT that ALL HD-DVD players decode at least 2.1 TrueHD, the Xbox360 Add-On is no exception, and it does decode the codec, which is why you get sound, however the system cannot produce that sound as it is and must re-encode to DTS or DD.

If you were to select a TrueHD track on an HD-DVD movie and the player did not handle TrueHD in one shape or form, you would get no sound. The reason being is internal data paths have a low max bandwidth, especially for the sound pass to the HDMI bridge, so the TrueHD decode would be too high a bitrate to pass, which is why the Xbox360 needs to re-encode to a lower codec for bitstream output to an AVR.ĭolbyTrueHD does not have a "Core" packet structure on HD-DVD like it does on Blu-Ray. Well just because I feel it is a misconception, the Xbox360 HD-DVD drive DOES actually read and decode the TrueHD soudtrack through the systems software based HD-DVD playback system, however the player then re-encodes into DTS at 1.5Mbps. So if that is any sign of things to come, it's something to consider Just to note, Pan's Labyrinth comes out very soon and it has a 7.1 DTS-HD:Master Audio soundtrack. So those are the two safest bets for HD-DVD players. Your TX-SR805 would finally have a chance to use its own decoders With the bitstream output of the XA2 or A35, you can have up to 7.1 channels and ANY audio format. Bitstream just means that the player leaves the audio alone and passes it along to your receiver via HDMI 1.3. None of the HD-DVD players can decode the new DTS-HD formats, they can only extract the regular DTS audio "core" from the -HD versions.īut the HD-XA2 and HD-A35 can both output bitstream audio. There are also the two new DTS formats: DTS-HD:High Resolution and DTS-HD:Master Audio. We haven't seen any 7.1 soundtracks just yet, but there's a chance they could be coming.

It sounds as though you weren't aware that DD+ is a significant improvement over regular DD and TrueHD even more so.ĪNY stand alone HD-DVD player can internally decode both DD+ and TrueHD and it will output it as 5.1 PCM, giving you the full glory of the new DD+ and TrueHD soundtracks.īottom line: try and sell your add-on to someone and go buy a Toshiba HD-DVD player.Īlso keep in mind that ALL HD-DVD players are limited to 5.1 channel internal decoding.
With a receiver as good as the TX-SR805, you are really robbing yourself of the higher quality audio of DD+ and TrueHD.
Either format is converted to either regular DD or to DTS. Yup, sadly, the HD-DVD add-on for the Xbox360 cannot handle the DD+ or TrueHD audio that is found on every HD-DVD.
