Title:
  DVD - 'attempt to access beyond end of device'

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  My wife is a DVD maven, and has been watching DVDs using an AMD64x2
  shuttle running Jaunty Mythbuntu. After watching a DVD for some time,
  it the player will about somewhere near the end of the DVD, usually
  with the last 2 chapters being unplayable.

  Using Ubuntu linux-image-2.6.28-13-generic via libata sr0 device AND
  kernel.org 2.6.30.2 /dev/hdc IDE device xine will stop suddenly, with
  a "libdvdread: Can't seek to block XXXXX" - some large number.  Also
  mounting DVD and reading last VOB file on disk results in:

  UDF-fs: Partition marked readonly; forcing readonly mount
  UDF-fs INFO UDF: Mounting volume 'LHOP_2_VOL3', timestamp 2004/10/05 01:52 (1000)

  This has happened repeatedly.  I have swapped the DVD writer out, and
  it still happens.

  Here is debug information:

  shalom: -grantma- [~] 
  $ uname -a
  Linux shalom 2.6.30-amd64-mag #1 SMP PREEMPT Wed Jul 22 19:00:37 NZST 2009 x86_64 GNU/Linux

  shalom: -grantma- [~] 
  $ 

  This bug occurs with both linux-image-2.6.28-13-generic (/dev/sr0) AND
  my own kernel based on 2.6.30.2 kernel.org source (/dev/hdc) - There
  is a real repeatable problem here - you have to sit down and watch
  hours of DVD to find it.  This occurred with a Pioneer DVR-110D  and
  an LG GH22LP20 DVD writers.
