Can I play a multichannel hybrid SACD on my pc in 5.1 surround. If I can do I need a separate program to do so.

The drive I am using is an Asus DVDE616P2 with firmware upgrade v107. I am using creative Inspire 5300 5.1 speakers on a Creative SB5.1 Live digital soundcard, which is connected to dvd drive with a digital audio cable.

I know my comp plays DVD-A 5.1 no problem (although soundcard is 16bit and dvd is 24bit so I loose a little in quality). I use my comp as a media centre so don't want to buy a SACD player, unless I can get a SACD compatible internal IDE drive that is good.

No PC plays the hi-rez layer of SACDs. You can only play the CD layer of hybrid SACDs.

SACD is a closed format. For copyprotection reasons, a PC should never have access to the digital hi-rez signal.

thanks for the reply. Nevermind, I bought new NIN downward spiral hoping to get it in 5.1. I will just wait for a DVD-A for that I guess.

I do see your copy protection point though, and agree in many ways. There are always ways round it even if have special protections on PC stuff. I always pay for stuff I use myself even though I know ways to bypass copy protection, most people are not as honest as me though.

DVD-A has the same restrictions on PC, but Creative gets around it by doing all the processing onboard the audio card so no proprietary information is supposed to be exposed to digital sniffers. Theoretically this could be done with SACD as well, though you would need a special drive to read the SACD layer from the Disk (not a problem with DVD-A since it is stored on a standard DVD).

Are there any PC drives that actually CAN read SACD (both multichannel and two-channel) ?

There are some older drives (htpc) that can read the TOC of sacd layers and display the files listed of the disc. however you have a number of secondary problems..ie.if the disc has encryption and the file struture is not a recognized pc format (bitstream)....
There was a report that Philips were considering a legal playback system for pc...without the need for hardware(chip)..IMO it would be easier to get a soundcard with a sacd chip included...again Philips/Sony licensing would be required...,This may well occur if "home made" dvda takes off.....unlikely.....
Whilst the manufacturers of sacd equipment are forced to provide "limited" digital offtakes....theres no reason for the consumer If technically gifted to accept this limitation.ie they can change this...PS >>> No information will be given...Dave

I think it,s quite out of place discussing ways to get around copy protection on this site. After all the idea is to propagate SA-CD. Every one is complaining about to few new releases. New releases, especially new recordings cost lots of money, this selfish idea of copying the discs instead of buying them, deprives the people involved of their income. This is certainly not what will make the record companys invest a lot into entirely new technology and new recordings. A main factor for labels to push SA-CD is it's safety, why should they continue if it turns out not to be safe either but only cost more, and, out of all, the encouragement to get around copy protection coming from readers of an SA-CD fan-site !!!

I couldn't agree more. Let's close this thread now.

I don't think (at least I hope) that nobody is advocating copying discs instead of buying them. The original question was solely related to playback on a PC. Also, it is not illegal to make a copy of a disc you paid for if it is strictly for personal use. I don't think anybody is advocating illegal copy and distribution of SACDs. For some people, it would be nice to have the option to play them on a PC.

Positiv thinking there ! I hope you are right, but it does'nt make much sense to me wanting to listen to high resolution sound on a PC, not exactly a high end reproduction chain, is it?
