So.... I've been reading about TrueHD and its likes lately, most I have found out is that it only passes through HDMI 1.3... so how will it work with HTPCs, since it's DVI ?

Neg. It works over analog with an X-Fi soundcard which outputs 24-bit/96kHz in 7.1 channels. I'm using the above cables that the previous poster recommended and it works great. PowerDVD itself does the DD+, TrueHD, and DTS-HD decoding.TrueHD as in the Sounds from HD-DVD and Blu-Ray players can't be done on current HTPC's, as there is no soundcard currently that can process that information. As you said, you need a soundcard with HDMI v1.3 to do this.
All sounds (assuming you are going through a soundcard and being passed off to your reciever) will only be 5.1. So TrueHD sounds get downgraded to normal DTS.

I don't use optical, I use analog. But every indication I see, it doesn't "downres". In the information tab in PowerDVD it shows full range, and when I pull up the in movie information overlay, it shows the full bitrate MLP audio track playing at greater than 1.5mbps. If I use the creative driver settings to manually force 16bit 48khz, the sound is slightly muddied more and you can tell you aren't getting full range audio. The difference is clear from what I hear, so I am very skeptical of what a $12 per hour foreign email tech is saying.Perhaps you should read up more W1retap. Here is some prime examples about HD Audio in a HTPC environment:
This thread is titled: FACT: You cannot listen to High Resolution HD audio via PowerDVD
http://www.avsforum.com/avs-vb/showthread.php?t=892863
Here are some notable quotes:
"No, PowerDVD will always downsample if the source is higher that 48/16 and it doesn't support DTS-HD MA yet. Even if AACS has been removed."
"The conversion from the TrueHD to the PCM isn't exactly a 1:1 copy. TrueHD is usually 24-bit 96kHz, while the SPDIF output you are getting from PowerDVD is 16-bit 48kHz. "
If your interested, you can read up on the trials and tribulations of PowerDVD (which is currently the only way to play HD-DVD and Blu-Ray on your PC, that is widely supported):

There is an alternative to PowerDVD that does HD-DVD and Blu-Ray, from Arcsoft which you can read here (not ready for English prime-time yet, but the company says soon):

Yes.Do you have to have a 7.1 system to listen TrueHD anyway ? All the links I have read is always referring to 7.1 sound systems.
He's blowing smoke. The latest PowerDVD update patches it so that it doesn't downgrade the audio, it use to be a issue but it's not now.Thanks for the info Powerhouse2k. I didn't realize the sorry state of PC HD audio.

IIRC it is, so what? This isn't a new thing, anyone that has played with HD/BR on the PC knows that the whole process is inherently broken and held together with the tech equivalent of duck tape. One thing gets fixed, the fix breaks something else. If you can't deal with that then I highly suggest that you go out and get a stand alone player.So which version number is this? Could it be the same versions that now NO LONGER ALLOWS playback of HD material from your Harddrive? Which is fine if you want to just pop in a disk and play it straight from your HTPC DVD player without copying the Movie to your Hard Drive.
Point me to a stand alone player that does the same things as an HTPC.But then, wouldn't a stand alone HD-DVD/Blu-Ray player do the same, but with full support for TrueHD as well?

'No. PowerDVD Ultra does full res TrueHD and DTS-HD.

It cannot do it over optical due to bandwidth limitations, therefore must be downsampled. That is the circumstance where obviously it gets downsampled.
Again, when I playback TrueHD audio tracks over analog with the Creative Theater Cables I can go into the audio track info and see in real time the bitrate it is running at (~1.5mbps), and then I can switch back over to DD+ (~640kbps) and notice a difference in sound quality. Please, stop spreading the rumor that one know it all started on AVS forum. Everyone gets suckered into it. If you really do believe it, I'd take it up with Cyberlink in court and you could win yourself a hefty lawsuit.
I'm using the Onkyo TX-SR605 with Yambeka 7ch speakers and a SB X-Fi Xtreme Music card connected using the Creative 7.1 Theater Cables. It is a pretty inexpensive setup, but i can notice a difference. In movies that contain the TrueHD and DD+ soundtrack, when I switch over to TrueHD the highs and mids that stick out in action scenes are more defined. The difference isn't huge because the ear isn't capable of picking up all the little differences, but it is noticeable in certain scenes of movies if you flip back and forth to compare.
If you set it up with 5.1, everything will map to the correct speakers just fine assuming you plug it in correctly. In the sound card setup, you choose the analog 5.1 speaker option.if i setup my speakers as 5.1 will anything other then the 2 side channels be changed?

No, nobody admitted anything. It was an $8 per hour tech in their India email support team that said that many many updates ago. My ears can tell the difference when I switch audio tracks, and it displays the proper bitrate for the lossless track, so certainly it appears to be working just fine. Dozens of other people on HDbits also have the same experience as I, so I'm not a one person wonder. Cyberlink advertises on their website that it fully supports all those audio formats. If you want to take up a legal battle with them, be my guest. I really don't know what your vendetta is, but if you need any further proof than that, it is going to take more time to prove than you could imagine. You'd need software and hardware layer based proof that I doubt they are willing to give out due to copyright and piracy concerns.
As far as I'm concerned, the issue was cleared up or never existed in the first place. He said it was a bug but the AACS doesn't require downsampling. Every indication I as well as dozens of others are getting, we hear the full definition audio, and it is a pretty apparent difference as compared to the DD5.1 tracks of regular DVD's. If you open up the PowerDVD information tab in the config while you are playing back uncompressed audio from an HD DVD, it clearly shows it isn't being down sampled, and it surely doesn't sound like it.

hmm interesting info, thxman you've made me a bit happier
so what kind of reciever would take in 5.1 or 7,1 analog signal? do most of them? over a regular 5.1 system, could i hear the difference from dd+ to TrueHD going through the method that you use, or do you have some crazy speaker setup ?
