Hi everyone,
I often read here but rarely post as I always find the answer to my question in other posts. But unfortunately, I have not bee able to find an answer now so I have to ask.
I just got a music DVD-Video which I want to convert to CD-Audio. The sound track is 96 kHz / 24 bits LPCM. I tried to demux it directly with DVD Decrypter, but I always got a vob file, not a wav file (I even checked the header to verify), so I extracted the audio with DGIndex. I tried to downsample it to 44.1 kHz / 16 bits with BeSweet, but it wouldn't work as BeSweet would always assume it was 48 kHz, so I used ssrc from the command line and it worked. The original wav file and the new wav file have the exact same lenght close to the 1/1000 second. To create my cue sheet, I used the file created by DVD Decrypter (Chapter information - OGG), which is the same that can be created by Chaptor-X-Tractor with the OGG preset (with a 0,001 second difference, which doesn't matter). I the created a cue sheet with Chap2Cue. Everything is OK up to now.
When I mount the image with Daemon Tools and I play it EAC or any other CD player software, the track are more and more offset compared to the audio (4 seconds at the last track). I checked with Audacity to find the exact track change positions to confirm it. All tracks are off by approximately 0,13%, which amounts to 4 seconds at the end of the disc.
The difference between 30 fps and 29,970 fps is 0,1%. Could it be related? Is there something I could do for the tracks to be in sync without having to correct the cue sheet manually?
Thanks for your help.
