As most of you know, I use Linux at home, and watch DVDs on my computer. However, my setup appears to be hypersensitive to damage to the disc: scratches or smudges that Windows Media will cruise blithely over, with at worst a little jerkiness, cause my DVD playing software, whether Totem, Xine, MPlayer or VLC, to judder, frame by frame, to a standstill, and then to give up and kick me out of the viewing altogether (which makes it very annoying trying to find the place again afterwards).

/var/log/messages reports:

Anybody got any idea what I can do about this (or even what keywords to google for for help)?
