It seems that a sector on the disk might be bad. Windows reads around
the sector somehow is my guess. I'm not very familiar with xine. I use
either mplayer or videolan (aka vlc). What I would try to do is, run
the disk without mounting it; just tell your program to read directly
from the device.....I'm not sure if you are already doing this, if you
are try the reverse: mount then play the .VOB files.
