8 # Description: This script wraps a number of linux utilities to
9 # create a recipe for ripping protected DVDs, circumventing
10 # ARcoSS and CRC checksum error protection schemes used on many
11 # newer DVDs. Edit as appropriate for your needs. I use this to
12 # backup DVDs I own, and do not condone any other activity it
15 # Known Issues/Limitations:
16 # - Mirror mode is always done in ISO mode
18 # Package Dependencies (apt-get install these for example):
19 # lsdvd dvdauthor gddrescue dvdbackup tovid mencoder mplayer genisoimage libdvdcss2
21 # Specific Executable (program) Dependencies (must be found in $PATH):
22 # volname makexml lsdvd dvdauthor gddrescue dvdbackup mencoder mplayer mkisofs
24 # Optional Dependencies:
25 # lookup imdb info/posters for mythvideo: http://www.mythtv.org/wiki/Fill_mythvideo_metadata.pl
