Comment(by noisymime):

 I have confirmed this using both the vanilla Ubuntu 8.04 build as well as
 manual build using options in previous comment (ie cpu=i686).

 One of my test machines is a P4 with hyperthreading. Switching
 hyperthreading on (in BIOS, resulting in the system seeing 2 CPUs) causes
 segfault during DVD playback. When this is switched off in BIOS however
 (With no other changes to the system, including kernel), then previously
 problematic DVDs will play without any issue.
