Dear,
I would like to get more information about the sound quality that goes out of WinDVD Pro 11.
I understand that DTS-HD master audio from a blu-ray movie is 96Khz/24 bit.
If I check the info when I play a movie is says 48Khz/24bit.
Does PowerDVD 11 Pro downgrade the audio of the blu-ray if I use it with a analog connection ?
My system and sound card support 96Khz/24 bit sound output.
Thank you
Sebastian

Re: Output Sound Quality
I don't know, but DTS-HD has a regular (lossy) DTS component and a correction component that allows lossless decoding.
All Blu-Ray players (and player software) can play all of the formats, but they are not required to play them all losslessly.

Wikipedia says:
Combined lossless/lossy compression.
When played back on devices which do not support the Master Audio or High Resolution extension, it degrades to a "core" track which is lossy.[5]
According to the DTS-HD White Paper,[6] DTS-HD Master Audio contains 2 data streams: the original DTS core stream and the additional "residual" stream which contains the "difference" between the original signal and the lossy compression DTS core stream. The audio signal is split into two paths at the input to the encoder. One path goes to the core encoder for backwards compatibility and is then decoded. The other path compares the original audio to the decoded core signal and generates residuals, which are data over and above what the core contains that is needed to restore the original audio as bit-for-bit identical to the original. The residual data is then encoded by a lossless encoder and packed together with the core. The decoding process is simply the reverse.

Re: Output Sound Quality
Yes, I know that. I took a look at the dolby website and they state that 96Khz/24 bit is the maximum BUT if it is used is a other question. So the 48Khz/24 bit I get to see in the menu under information is the sound on the blu-ray and if I set windows to 96Khz/24 bit the sound from the blu-ray should get upmixed by my sound card or am I wrong ?
