Help..No audio on first part of movie and Last

Strange issue! I have ripped the movie 10 times (resident evil). Everytime I rip it for some reason the sound is gone except in the 2nd vob. There is 5 vob’s for the main movie and the 2nd vob has sound and none of the others. I have tried ripping all of the movie and just the parts I am supposed to. Nothing works. Any suggestions would help. Also if it helps I have tried dvd decrypter and smart ripped in file mode only. Thanks for any help.
