Ok guys, here is a real brain teaser. Please help me with what is going on here. I have PDVD9 set up, drivers set up...seems like all is configured correctly, but is it?
I have purchased and ripped the a few Blu-Ray's recently. For this discussion we will focus on Transformers 2 and X-Men Origins. I have run both the ripped versions (via AnyDVD to get first rip to ISO, then via DVDFab to only keep the main video and audio tracks) and the disc versions. The ripped version obviously coming through the HTPC with 5750 and the aforementioned drivers through PDVD9 and the disc version is over my Panny DMP-BD35. I wanted to do a side by side for audio testing and this is what I got.
My AVR is a Marantz SR8001 with firmware upgraded. It receives LPCM 8 channel but can NOT receive bitstream of DTS HD MA or TrueHD (does not support the newest codecs). I am actually indifferent on this as I prefer to run LPCM from the player to the AVR (i.e. let the player decode but keep in digital domain via PCM) as this gives me more flexibility on using different post processing modes in the AVR itself (i.e. with this AVR I can use THX Select 2 mode to matrix a HD 5.1 PCM to use all 7 speakers....whereas with some AVRs I tested if you bitstreamed a 5.1 HD audio track the AVR would not allow you to matrix it out....I know it is likely equipment dependent.
Ok, anyway, heretofore I have always used my stand-alone player. For 7.1 movie tracks I run it in Auto Surround mode and for 5.1 HD tracks that come across as LPCM 5.1 I often choose to matrix via THX Select 2 so I can get use of all speakers.
Back to my test. First, both discs state on their covers that they are DTS-HD MA 5.1. Yet when I played both in the Panny BR player they registered on the AVR input screen as 7.1 ....making me think I was really getting LPCM 8 channel from the Panny vs. what I expected as LPCM 6 given the disc covers stated 5.1. In Auto Surround mode (or Source Direct, etc.) I do get audio through all my speakers (i.e. with no need to matrix)
Now, when I played the rips via PDVD9 I can only get 5.1 audio across (i.e. LPCM 6). That status screen on the PDVD9 player shows output of LPCM 6 rather than LPCM 8 (by the way, will PDVD9 support up to 7.1 on the LPCM? My AVR will register on its input status screen whatever I have the Audio Device Manager/Configurator set up for in Windows for the HDMI output device. If I choose 7.1 in windows than the AVR status screen would lead you to believe I am getting 7.1 across. If I choose 5.1 in windows then the AVR will not show any signal coming into it for the Surround Backs and it just looks like 5.1 is happening. But, from an actual output of what is coming across (not what the status window shows), if I have it set up as 7.1 then I only get 5.1 across. That is to say that it appears on the disc over the Panny I am getting more than what they promote on the disc cover, but the same image ripped I am only getting 5.1. Of course the problem is that with the 5.1 on the ripped images, the only way to get to 7.1 is to matrix it out. This can be done, but I thought that this SHOULD be consistent between the two set-ups. Because of some other work around that Windows supposedly requires, as it is I need to move the windows configuration setting to 5.1 so that I can also force the 2 rear channel paths through the sides rather than the backs.
