Hmm. I'm going to have to try this when I get home. I wonder if this will be a good replacement for MPC-HC. I'm still a bit iffy on MPC as I've still trying to figure it out. VLC always seemed like a great player.

So VLC finally made it to 1.0 impressive.

So what does it mean when it says it supports the codecs? Will it decode 7.1 to analog soundcard outputs? Can it just extract the core track and decode that? LPCM out the HDMI?

TrueHD doesn't have a core track.
All the setops do real time re-encode to DD

DTS-HD MA does have a core track, but they don't support DTS above basic DTS.

As far as once the audio is decoded by the player it send the PCM to the windows mixer (assuming it's not in wasapi mode) and windows mixer simply outputs it to whatever configuration you have (7.1 ananalog, 2 channel analog, 7.1 channel HDMI, DD Live re-encoded).

I wonder if the new VLC 1.0 can use IFO files to play VOB files in sequence from hard disk? All the 0.x versions failed to do so, at least as far as I know.

True, but a TrueHD audio track in a BD movie usually (perhaps always) has an 'embedded' AC3 audio track (as everybody notices it with eac3to). This is a real AC3 track, not just real-time encoding from TrueHD to AC3. This is clearly seen using ffdshow Audio Decoder with the following settings:

- Codecs > TrueHD: disabled
- Output > Pass-through (S/PDIF, HDMI) > AC3: checked

When playing back a M2TS file with a TrueHD track, I see:

So the 'core/embedded' AC3 audio is extracted from the TrueHD track and sent to the receivier (I see the 'DD' indicator light up in the receiver).

I believe it is a requirement of Blu-ray (but not HD-DVD) that all TrueHD tracks have a "hidden" AC3 track. This is not a "core" but fulfils the same purpose. The only practical difference I think is that a player need not know anything about DTS-MA to find the core (eg. ffdshow can play a DTS-MA core now). However the "player" needs to be sufficiently aware of Blu-ray structure and TrueHD to know to look for the hidden AC3 track.

It's not always hidden (for instance Warner puts it in the audio menu and even defaults to DD) on BD and you are correct that HD DVD had TrueHD (optional on BD) as a mandatory codec so no DD was required.

Yeah, sorry. I meant if TrueHD is included a DD track must always be present, either explicit or hidden.

I don't see the "DTS->SPDIF" selection anymore and, as it happens, my DTS .WAV files are playing 2.0 and not 5.1. Even when I "correct" the "Audio Device" to 5.1, it streams 2.0 (although, interestingly, it sounds much different than when "Stereo" is the device). AVR does not recognize any encoding or multichannel. I have the AC3 filter installed. And I have the "Use SPDIF whenever possible" selected." I tried both WMP and VLC- same problem. My ripped DVDs play 5.1 fine over the same connection. I do not have FFDShow installed.

I'm obviously missing something. These same .WAV files burned to a CD are recognized as "DTS" by my AVR when played on a bitstream-HDMI multiplayer.

The main advantages of Slyplayer are:
- it will play full Blu-ray discs, with menus (HD-DVD without them)
- it will use Reclock technology for judder-less playback, 24p @50Hz (for PAL displays) and PAL @ original 24p, for 24p-capable displays
- It will output HD audio (LPCM over HDMI) without downsampling

No other DRM-free player offers the first two of these or even has them on the horizon, although the second can be achieved by using Reclock with a DS player (so not VLC).

Wait. So, MPC-HC can deocde DTS-HD MA, but not TrueHD. Now VLC can decode TrueHD, but not DTS-HD MA. Is this correct?

No opensource players can decode DTS-MA. MPC-HC will decode the core.

MPC-HC can decode TrueHD by using ffdshow audio decoder. Still an essential add-on to any Directshow player.

Thanks for the clairification. I guess I'll be sticking with TMT until Slyplayer or something else that decodes both TrueHD and DTS-MA to LPCM comes out.

It hasn't been cracked, so you need a commercial licence. Slysoft have said pretty clearly they will support it, so either they have cracked it or they intend to buy a licence, which will be tough for a free product. But then it requires AnyDVD to work and that is not cheap so they do have a revenue stream.

Frankly speaking, VLC is a crap as far as HD playback is concerned. Stick to MPC-HC for this purpose. SlyPlayer is totally different from them, ultimately it's a BD player.

I've been trying the 0.9.x releases for months on my admittedly slow old Athlon on my main PC. Never used it on my HTPC. The performance has consistently been terribly, whereas 0.8 was blazing fast -- so I kept going back to 0.8.6. Even at vers 0.9.9 it was bad. Its a little ridiculous that 0.8.6 could play SD MPEG-4 ASP at less than 10% CPU, and h.264 at around 20%, while the 0.9.x releases take forever to load, hog 35%+ CPU playing an old DivX, and can't even start the video smoothly, displaying distorted colors and picture for several seconds and occasionally just choking on videos.

Then I downloaded 1.0.0 and it runs really well, almost as fast as 0.8.x with no real issues. Go figure.
