ATI DVD player going out of sync

Some users of the ATI DVD player report an annoying problem of sound becoming more and more out of sync with the image (it starts Ok, then image arrives before the sound).

While it may not be always from the same origin, it appears that a number of VIA-based chipsets (and possibly others) are sensitive to a BIOS parameter: PCI Master timeout (aka PCI latency time). When set to anything higher than 0, the problem occurs. Reset it to 0. This has a good chance of improving dramatically (or solving the issue).

Beware! Not all BIOS give you direct access to this parameter. You may have to upgrade your BIOS to the latest version. Or you may want to use TweakBIOS (for the growing number of supported chipsets).
