Blu-ray Dolby / DTS TrueHD
fitbrit:
Perhaps this isn't the answer you're looking for,a s the discussion seems to have moved onto gaming:
The new ffdshow versions can decode TrueHD and DTS-HD formats. You can then decode to LPCM, strip to core AC3/DTS or Bitsream depending on your audio(video) card and connections. Currently, I am able to listen to mkvs with TrueHD sound in MC, their downconverted to AC3 and sent over spdif to my speakers on my desktop. Soon, with my newly purchased GeForce 240, I'll be using LPCM to my receiver. Eventually, when nvidia sorts out bitstreaming I'll upgrade again.
No fancy sound cards.
No proprietary software.
Just MC, hardware accelerated mkvs/m2ts files and lossless sound to come. :)

Thanks for the input.
So what's involved in putting in a Blu-ray movie (disc, not download) and playing it with the TrueHD output as AC3 over the SPDIF?
Should I be able to install AnyDVD-HD, then play files directly off the disc with Media Center using ffdshow as the decoders? Last time I tried using ffdshow for video decoding, I couldn't get any hardware acceleration running.
Thanks again.

I'd be interested in this as well. And...

Me too, but I've heard that the new tryouts builds might support DXVA. Is this true? (I suppose I could look over at AVS or Doom9, and maybe I will tomorrow.)

I just gave it a try.
Fullscreen playback of a 1080p Blu-ray uses about 10% of the CPU with a newish FFDShow on an i7.
I remember last time I tried it buried my Core Duo which is almost as fast per core. So either it's using acceleration or it's multi-threaded enough to use more than one core.
So that removes the video obstacle.
Then the only question that remains is whether it will be able to consistently output the high-definition audio as AC3 over SPDIF. I understand this won't sound quite as good as the HD formats. I don't own many Blu-rays (I rent), so I can't test this very well right now.

Yes, the new FFDshow tryouts do support DXVA. However, I still use CUDA for h264 via CoreAVC. Don't forget that FFDSHOW has separate audio, video and subtitle filters. You can mix and match as you need. I don't know about using a disk, but for files you do the following:
(This works for me, but may not be the only way to do it)
Install a new ffdshow
You also have to install the Gabest splitter (MPC-HC's internal)
You also need MPC-HC audio renderer.
Make sure ffdshow has TrueHD etc. enabled.
You also have to enable the Dolby Encoder.
With SPDIF as your chosen output, the above should work. It's for special cases like this that every now and then, I implore MC to allow us to set filters on a per-file basis. We can still have defaults for each filetype, but also allow each file to have exceptions. It makes little sense when an mkv container can have tons of different format combos within it, to have a single default combo of filters for all mkvs. Tons of discussion on this here:

For Bitstreaming using an ATI 5xxx series card:
--- Quote from: Doom9 Forum ---Setup :
- Install FFDShow Tryout revision 3161 or greater, 32 or 64 bits
- On Vista : you will need the MPC audio renderer. It is very recent and in early stage but it is functional.
- On windows 7 : directsound renderer should work on most bistream formats. Otherwise use the waveout renderer or MPC renderer
- If you have a xonar : won't work with directsound renderer, the best is to use the the arcsoft renderer (on a dos window in administrator mode : regsvr32 (total media path)\codecs\asrenderer.dll). Otherwise try the waveout or MPC renderer (don't know if they will work)
- Player software :
1/MPC-HC : you will have to grab a very recent version of MPC-HC (revision 1413 or greater). If you don't have the right version the MPC mpeg splitter will break the DTS HD streams and the MPC renderer won't work
2/Other directshow players (WMP,...) : you will need MPC-HC *recent* standalone filters (revision 1413 or greater). Just register MPC audio renderer and MPC mpeg splitter. For MKV Haali media splitter should work too.

Now the only way I think it'll work with a disk is if you open the BluRay structure and navigate to the M2TS files. I found setup to be easier in MPC-HC than in MC, because MPC-HC has most of the filters required internally. So, rather than download all the standalone MPC-HC filters, you may just wish to change the filetype options in MC to launch MPC-HC when playing M2TS files. I didn't want to do this, so I continued to mess around until I got MC working with the tips in that massive thread.
