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:
19 # lsdvd dvdauthor gddrescue dvdbackup makexml tovid mencoder vlc mplayer genisoimage
21 # Optional Dependencies:
22 # lookup imdb info/posters for mythvideo: http://www.mythtv.org/wiki/Fill_mythvideo_metadata.pl
