Most probably a scratch on the DVD making a sector unreadable.
libdvdnav (used by xine) cannot handle any sectors being unreadable on 
the DVD. Currently, this is mainly due to the linux kernel going a bit 
wild when it finds an error on the DVD.
It might be a bug in libdvdnav, so if you have enought disc space, use 
the dvdbackup tool, and see if it can read the whole DVD and copy it to 
your hard disc. That way we will know if it is a sector error, or a 
libdvdnav bug.

In the xine config screens, you have boxes under the audio tab (might 
need expert config mode, see gui tab).
audio.alsa_front_device:front
audio.alsa_surround40_device:surround40
audio.alsa_surround51_device:surround51
These will access the first sound card.
Changing them the following will use the second sound card.
audio.alsa_front_device:front:1
audio.alsa_surround40_device:surround40:1
audio.alsa_surround51_device:surround51:1
