View Full Version : Audio sync issue with "Star Wars The Clone Wars"

I have ripped Star Wars The Clone Wars (NTSC Region 1), the new animated one, with the entire disc with the following:
1) DVDFab
2) DVDDecrypter + AnyDVD
3) DVDShrink + AnyDVD
4) AnyDVD's ripper
After i demux the audio and video with PgcDemux, they become out of sync. PgcDemux says there is a -9ms delay, but there actually is a far larger delay (don't know how big, cuz i can't get it back in sync:p). I also have tried demuxing with dgindex, but to no avail. To test if they are back in sync, i have been using this AviSynth script:

a=DirectShowSource("VideoFile.m2v")
b=DirectShowSource("AudioFile_80.ac3")
AudioDub(a,b)

My question is A) how do i find what the delay actually is, B) what am i doing wrong that is screwing up the audio, or C) does this disc have some new variant of copy protection that is messing it up (i know for sure that it has something other than CSS). Any help is very appreciated. Thanks in Advance!

Make sure you are using the latest AnyDVD BETA: 6.4.8.4 (http://http://forum.slysoft.com/showthread.php?t=22379). Rip the DVD with the AnyDVD Ripper.

This DVD does have a fair amount of copy protection on it, not sure if it is anything horribly new though.

Tiny cells often mess things up. I'd trust PGCDemux of -9ms (although that is a funny number). There is probably an audio pack at the start to ensure a low delay that might have been cut out.

Oftentimes, if tinies (or other cells are removed) are removed, the audio delay can get outside acceptable limits (spec of +/- 300ms). I saw one the other day of -950ms!!! In this case, use Delaycut to realign the audio and remux.

Hi!

Rather than assume anything, I'll ask - What is it you are attempting to accomplish that requires demultiplexing?

FYI - After reading your post, I used MPEG Mediator to convert my DVD95Copy Pro rip to both an old DivX format and 3IVX format. Both videos are in perfect synch...

I will try that.

@blutach
I was thinking it could have been something along those lines, although i didn't fully understand how that works. I will try Delaycut.

@setarip_old
I am burning in the soft subtitles and cutting a few words out for a younger person. I will also try converting it to DivX and see if it becomes out of sync.

Thanks.
