regman,
My understanding is that the Toslink will only carry the legacy DD or DTS sound tracks. It apparently does not have the bandwidth to handle the new audio tracks although Rodolfo says it is a somewhat higher bit rate DD or DTS than the DVD format itself. Still, it is a big step down from the lossless format audio streams.

Before all this your SD DVD audio encoder cup was 1/2 full due to compression and now with HD disc it is 100% full and that is significant in theory and clearly audible in practice. Bear in mind not all movies have HD audio soundtracks but they are giving us what ever they used and that is being faithful to the source. What more could you want?
What I don't like is the movie claiming it has an HD audio soundtrack when it obviously does not. I wish instead they would say studio master audio or something similar inferring you are getting the best it is. It still sounds good for marketing and fairly represents what you are getting.

Richard,
Could you elaborate on that somewhat? If this is already covered in another thread or section, you could just post a link.
When you say it previously was 1/2 full and now 100% full, are you talking about the 2x data rate that Rodolfo had mentioned for those legacy DD and DTS sound tracks? Are the legacy DD and DTS sound tracks always 2x the DVD rate?
When you say it is audible, I hope you mean in a good way, but it is not clear in the way you stated it. Are you saying that due to the 100% compression, there are audio artifacts that degrade the sound, or it is clearly better?
Also it would seem from your comment that sometimes the HD disc carries only possibly no better sound track than the original DVD did? I know some DVDs that I have run across only actually had a stereo audio track, even though it was encoded in the mandatory 5.1 DD sound track. Is this also true of the HD disc formats?
Sorry for all the questions, but I don't have an HD disc player yet and I'm trying to fully understand what the investment will or won't buy me...
Thanks,
AaronS

aaronstout,
Starting at the source in the studio.. That will be what ever they are using, from the best of 24/192 to CD quality, 16/44. Just like in our homes this sound recording now has to be digitally encoded and just like us there are limits in how large the bitstream can be. The size is controlled with either lossy or lossless compression and that process is what we know as DTS, DD and their HD codec ounterparts.
DTS and DD are lossy compression encoders. Your local cinemaplex uses the full bit rate they have to offer and that bit rate was designed for what the film medium can handle. I do not recall the numbers but for SD DVD that maximum bit rate is commonly cut in half so it will meet the storage limitations of the disc with video on it. HD disc does not have the storage problem and that allows them to provide the same bit rate for the bitstream that is provided for your cinemaplex as well bigger ones, the HD audio codecs.
Yes, the HD disc version sounds better and fuller just like SACD or DVD Audio compared to CD. If you compare soundtracks you will find sonic elements flat out missing on the SD DVD version!
The HD Audio codecs take all this to a new level as they can provide the original studio soundtrack in all it's glory without any loss.
A blu-ray disc, don't recall the title, said something to the effect of having an HD audio soundtrack but when you looked at the back it was 16/44 multichannel CD quality which is not HD for audio but did represent the studio master and therefore was high fidelity as it was faithful to the original.This is what I was referring to in my earlier post.
