Ripping DVD-A

[num-lock]

I got Queen - A Night At The Opera dvd-a recently, and I want to rip the PCM tracks so I can listen to on my pc without dvd. So far, I:
1.) Demuxed pcm using Stream Processing
2.) Renamed .wav to .pcm
3.) Opened in Cool Edit Pro

This is where I hit a snag. As you know, PCM is raw audio data, no headers means lots of guessing. Smartripper told me it was 96kHz, and 24-bit. So I opened with all the 32-bit (float) settings. When I opened as a 32-bit IEEE Float (0.24), it was solid noise, but in backgroud faintly and above normal speed, it was playing softly. ALl other settings gave just noise except one. The 24-bit packed Motorola PCM gave me complete noise on the left-channel, and right-channel perfect sound (the way it's suppose to be). I tried to off-set the data reading to see if that fixed other channel, but it turned both channels to noise. Did I hit the end of the road, or does someone know something I don't?

Shouldn't you open it with normal 96kHz/24bit pcm settings because that is what your pcm file is? Also is this pcm track the real dvd-audio portion or is it from the dvd-video. Because many times, I believe because I know the specifications allow for it, dvd-a is encoded with a lossless compression called MLP. So, if it is MLP encoded, you will need an MLP decoder which will probably cost a good sum of money.

No, its from DVD-Video part, I skipped the MLP and DTS and went straight for PCM. Also, there are no plain 24-bit modes. There are the 32bit IEEE Float modes, then an Intel packed and Motorola packed 24bit mode. Intel didn't give me nothing, motorola gave me one channel, as I said.

Just came across something. I tried Intel packed 24-bit with an offset of +1, and it gave me left channel perfect and right channel noise, and I pieced 2 different channels together. I then found out that they are same channel, not separate ones. Again, any help at all would be nice.

[Donny661]

Why did you rename the .wav to .pcm? Smartripper might add the correct wav headers.

[num-lock]

When it opened as a wav, it opened as a 48kHz and 16 bit, which gave me nothing but noise also. I'll see if I can change any settings to get it to open as a wav tho.

EDIT: still nothing

Anyone know how to change values in a wav header? The header is tricking program into thinkin it is a 48kHz 16 bit file, is there anyway I can correct it to 96kHz 24 bit. Or perhaps does anyone know how to strip the header off, it may be messing up the sync when I open as a .pcm

if you dont have a 24 bit sound card you cannot play it back without reencoding to 16bit
