I've been using VLC in Windows and Linux since v8.6c, and this problem has occurred with all versions I've tried.
Quite a few of my DVDs have this audio drift problem which makes the playback choppy at odd moments. Different DVDs have different places where the problem happens, but for any particular DVD the chop will occur in the same spots every time.
All the affected DVDs work fine with SMPlayer, KMplayer, and Totem.
Setup:
Windows XP Home SP 2 (VLC 9.8a)
Ubuntu 7.10 64 bit (VLC 8.6c)
Mepis 7.0 64 bit (VLC8.6a)
MSI K9A2 CF
AMD Athlon64 X2 5200+
4G ram
MSI Radeon HD 3870
Creative SB X-Fi Elite (Windows)
Realtek ALC888 (Linux)
PIONEER DVD-RW DVR-115D

In this DVD, the fault does not follow chapter changes. What's not apparent from reading the file is that the fault sometimes occurs a couple of minutes after the audio stream changes.
Some questions I have read before regarding this fault:
"Did you try deleting/resetting preferences?"
I have tried it, it does nothing.
"Did you try increasing the cache?"
Yes. Increasing the cache can help smooth out the chop a little bit, but it doesn't stop the problem from happening. And increasing the cache too much just makes the film take too long to load.
"Is this an MGM DVD?"
The majority of them are MGM, but I have two that aren't. One of those others is the first example, in fact.
"Is this a new DVD? Maybe it's a new copy protection scheme that we don't know about."
The affected DVDs range all the way from 2007 to 1998. I'm pretty sure that's not going to be the problem.
I hope you can get a handle on this problem. If there are any questions I've missed, ask away! I'll do my best to answer them.
