I thought this might be the better place to post this observation about TrueHD audio from an HD-DVD decoded on a 10 year old Pre-Pro. This is new to me, so perhaps this is old hat to many of you.
I just bought the Toshiba HD-A35. It's the first HD-DVD player for me and the first new player in 7 years. It's hooked up to a Plioneer Plasma so I am getting 1080i imagery and it's beautiful!
I only have 3 HD-DVD's, The Bourne Identity, 2001 and 300. I just got a Toslink optical cable for the audio and my observation so far have been amazing audio from Bourne and 2001.
After a making a few attempts, I finally got audio into the Pre-Pro via bitstream. PCM wasn't being accepted by the processor. What surprised me is that the Warner DVD of 2001 defaults to TrueHD audio. When I first got this stuff, my understanding is that my 10 year old B&K Processor could only take the audio that is downconvert to DTS. What is happening is the Dolby Digital Plus is being read and decoded as AC-3 by my processor and it sounded great in Bourne. But 2001 was a real treat. The processor actually appears to be accepting the TrueHD audio! And I tried the DTS setting in my processor, no sound, so it appears to be getting Dolby Digital.
As an unscientific test, I used an SPL meter to check the sequence when the teams walks into the excavation site near the Clavius crater to see the Monolith. I set the player to output in Dolby Digital Plus. The music there was pretty terrific, but when I set the player to TrueHD, the SPL levels jumped 5 to 8 decibels. It sounded louder. Did I hear a difference? Maybe, maybe not. But I liked it better in TrueHD. Though I realize this is not really TrueHD I'm hearing.
Since Bourne is only Dolby Digital Plus, it sounded great too, but was lower in volume. I am really curious now to get Top Gun or another disc that is TrueHD audio to compare. I am not crazy about seeing 300, but I suppose I'll check it out.
Anyone have similar experiences with other hardware decoding the audio? Maybe this is not so amazing? I am just surprised that it appears TrueHD is decoding, although a likely a crippled or detuned version. I didn't expect this!
