I just got the I Robot HDAD as well as a couple other DAD discs from acousticsounds.com - one thing I wanted to do was make CD copies that I could play in the car. I've been succesful with both DADs and every track except track 1 of 'I Robot', but it's giving me fits.

The workflow is like this - I extract the LPCM from the DVD-V side with vStrip (splitting by cell ID so there is one file per track), use LPCM24.EXE to make .wav files, compress with Monkey's Audio to save disc space, then use Foobar2000 to resample to 16/44.1 and write to CD-DA. This has worked for every track except track 1 of 'I Robot', when I run LPCM24 on it it says something about the length not being divisible by 12 and says it is 'truncating', then the resulting .wav file is nothing but noise.

I've tried importing the .raw LPCM files into CoolEdit, but no combination of parameters seems to work. I've been able to get either the left channel or the right channel to be intact, so I tried to remix them together by hand and I got a usable file, but I'm concerned that it's not 100% accurate because Foobar's spectrum analyzer shows a fair quantity of high-frequency content that I think is noise - it's all in the range where I can't hear it on the computer speakers, I'm honestly not sure I would hear it on the hi-fi system either but it still concerns me. There's no similar noise on any of the tracks that LPCM24 succesfully converted.

Has anyone else tried to do this? Could someone else give it a shot and see if you have the same problems? The track plays fine with WinDVD platinum on the PC and in my standalone player, so it's not a problem with the disc, it is something about the PC or the vStrip software that in this one case hoses up the file.

Optionally, could someone verify whether maybe the high frequency stuff I'm seeing in my hacked track is really there or if it's an artifact of my hacking at it? Who knows what weird stuff came out of all those analog synths...?
