  25       <div class="body"><p>Keeping your DVD collection safe from scratches and curious
  26 children fingers while still having it available when you want to see a
  27 movie is not straight forward.  My preferred method at the moment is
  28 to store a full copy of the ISO on a hard drive, and use VLC, Popcorn
  29 Hour or other useful players to view the resulting file.  This way the
  30 subtitles and bonus material are still available and using the ISO is
  31 just like inserting the original DVD record in the DVD player.</p>
  32
  33 <p>Earlier I used dd for taking security copies, but it do not handle
  34 DVDs giving read errors (which are quite a few of them).  I've also
  35 tried using
  36 <a href="http://people.skolelinux.org/pere/blog/Ripping_problematic_DVDs_using_dvdbackup_and_genisoimage.html">dvdbackup
  37 and genisoimage</a>, but these days I use the marvellous python library
  38 and program
  39 <a href="http://bblank.thinkmo.de/blog/new-software-python-dvdvideo">python-dvdvideo</a>
  40 written by Bastian Blank.  It is
  41 <a href="http://packages.qa.debian.org/p/python-dvdvideo.html">in Debian
  42 already</a> and the binary package name is python3-dvdvideo. Instead
  43 of trying to read every block from the DVD, it parses the file
  44 structure and figure out which block on the DVD is actually in used,
  45 and only read those blocks from the DVD.  This work surprisingly well,
  46 and I have been able to almost backup my entire DVD collection using
  47 this method.</p>
  48
  49 <p>So far, python-dvdvideo have failed on between 10 and
  50 20 DVDs, which is a small fraction of my collection.  The most common
  51 problem is
  52 <a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=720831">DVDs
  53 using UTF-16 instead of UTF-8 characters</a>, which according to
  54 Bastian is against the DVD specification (and seem to cause some
  55 players to fail too).  A rarer problem is what seem to be inconsistent
  56 DVD structures, as the python library
  57 <a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=723079">claim
  58 there is a overlap between objects</a>.  An equally rare problem claim
  59 <a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=741878">some
  60 value is out of range</a>.  No idea what is going on there.  I wish I
  61 knew enough about the DVD format to fix these, to ensure my movie
  62 collection will stay with me in the future.</p>
  63
  64 <p>So, if you need to keep your DVDs safe, back them up using
  65 python-dvdvideo. :)</p>
