Last VOB has slow audio

[danjx]

I've just ripped Tomorrow Never Dies and played it back from the VOBs to check if it looked OK. I noticed that the last VOB (5) has audio that is off-frequency, i.e. evryone talks deeper and slower than normal. I ripped the VOB again, but the result is the same. I've tried playing the VOB4 and letting the player proceed VOB5 normally but the effect is the same.

How should I handle this problem?
