ok latley i have been hearing alot about dolby digital Plus in the HDDVD vs BLU-RAY argument. blue ray uses or can use uncompresed pcm 5.1 24bit/92khz or whatever it is. shurley uncompressed is better than any DTS or Dolby digital track. on HDDVD they mainly use dolby digital plus i dont think ive seen one with a uncompressed audio track. i know there a space issues this could be why but im just think that uncompressed would be ten times better.right?
also relating to ps3. does ps3 convert all audio in 5.1 to dolby digital or dts sound. e.g. if i was listeing to the uncompressed pcm soundtrack would it translocate it to dolby or dts depending on what i sellect. same with dts hd and HD sound format does it convert them to standards?
Hmmm where to begin...
Both formats sometimes use uncompressed sound that sounds more like the original intent... = better. HD DVD's version of this is TrueHD, and Blu-ray is Uncompressed PCM. Neither one is really better over all..... especially at this time.
To basically answer your question, NO... you cannot send uncompressed sound and have it "unzipped"... not until HDMI 1.3 Recievers come out (and they arent out yet, and when they do they will be really expensive).... and youd have to use HDMI into the reciever and then into the TV.
The only way to get Uncompressed Sound and TrueHD now is to have a HDMI reciever that accepts unzipped sound.... A few of us here in these forums have them, myself included. We are enjoying the pleasures of uncompressed sound now.
If its not sent Uncompressed then its called "Bitstream".... its zipped - sort of like a file on a computer, so save space, but you lose quality. TrueHD and Uncompressed PCM are the other way around, you need special recievers and HDMI to send and recieve them... The cost more, HDMI 1.3 makes it more simple for people and cheaper (in the end).
Unless you have a HDMI reciever and are using it properly right now, you can only send your reciever compressed sound, like the older sound formats.

i dont have an hdmit receiver yet, but just playing the pcm tracks through optical is better than regular dolby digital and dts. the pcm track on the descent is incredible through pcm even without being lossless. the surrounds really kick in. i want to get silent hill to check that out as well.

Hmmm, well its possible that your getting a bit more information, but your not actually getting the actual uncompressed sound, it might just make it louder.

so ps3 can stream uncompressed from optical. my receiver can only recieve dd 5.1 and dts 5.1 or 7.1 etc never tried uncompressed 5.1 dont think it will do it does this mean i will get no sound at all from the ps3?
you can send sound when its picked as uncompressed but your reciever (unless its HDMI reciever) cannot actually use it, so by default it will output regular sound, not the uncompressed stuff. there no way you can do it, It doesnt matter if people say it sounds better or what, they arent getting the uncompressed sound.

so what it would output dd 5.1 or something

just set your PS3 in the sound options to AUTO and make sure to select optical.. then when watching movies with your PS3 stick to anything but the uncompressed PCM because you wont actually be getting it, just use regular DD or DTS.
