TIP DVD: Rip, Shrink, and Burn

#!/bin/bash
# rsburn.sh
# Rip Shrink and Burn.
# This script will extract, resize, and burn a dvd.
# Most of the material here was borrowed from: 
# http://forums.gentoo.org/viewtopic.php?t=71032

# Requirements:
# -dvdbackup
# -growisofs (dvd+rw-tools)
# -libdvdcss
# -wine
# -DVD Shrink (http://www.dvdshrink.info)

# Other requirements:
# -Adequate hard drive space (18 Gig?).
# -DVD burner.

# Todo:
# - Find a replacement for DVD Shrink that will preserve menus.
# - If DVD Shrink cannot be removed, automate it's
# use (http://www.dvdshrink.info/chetwood/  or 'Autoit' as a possibility).

# Changes:
# 12-12-2004 - edited script
# - To allow some error checking with DVD Shrink files.
# - Allowed more communication to user as script is processing to aid in debuging if problems arise.
# - Simplified some commands (origionally quick and dirty solutions, changes seem more appropriate).
# - Reorganized system variables for easy viewing/editing
# - Autodetection of both destination and source dvd drives are the same.  Eject and ask for blank DVD as needed. 


	# Set your variables to match what your system requires.  Mine 
	# is probably simpler than most.
	dvdsource=/dev/hda	#Source DVD drive for reading.
	dvddest=/dev/dvd	#Destination DVD drive for writing.
	ejectwhendone=y		#Do you want the destination and source dvds to autoeject when finished burning?
	deleteiso=y		#Delete the completed iso image when done.
	tmpdir=/tmp		#Default temp directory, you may want to stick it somewhere else. 
	winecdir="$HOME/.cxoffice/dotwine/fake_windows"		#A location easy to find while in DVD Shrink,
				# and a location to refer to when this script burns the dvd.  To keep things 
				# simple make sure this is c:\ in wine.
	winebin="$HOME/cxoffice/bin/wine --check --cx-app"	#Wine binary, location, and extra parameters.
				# I am using crossoveroffice, others may just use wine.

				# as wine sees it (or Pinnacle InstantCopy).  Origionally had
				# winebin and dvdshrinkexe in one  command but wine did not see
				# the location of dvdshrinkexe so I split them up.
