Problem with subtitles being out of sync with audio

Hello everyone, let me describe my problem briefly.

DVD decryption software - DVDFab HD Decrypter
Ripping software - AutoGK
Movie - Curse of the Golden Flower
Audio language - Chinese
Subtitle language - English

I’m trying to create an AVI backup of this movie. When I rip it using the aforementioned software the subtitles are out of sync with the audio, but here is the weird part, it’s out of sync for the first roughly half of the movie, but perfectly fine for the second half. I’ve tried decrypting and ripping multiple times, same problem. When watching the movie right off the DVD the timings are correct.

I’m using basically default settings, MainMovie rip from HD Decrypter, ripping into VOBs and IFOs (Not single ISO). AutoGK is just making a 700mb rip with no tweaks or anything.

Anyone know what’s up?
