You don't need to go through Shrink when making a backup of a backup. The encryption is already gone so any disc copy program should work if your first copy is OK. jerry
i used decrypter and shrink ,the media im using is memorex dvd-r 8x,4.7 gb,i never have had any problems with this media,I use it for everything ps2,movies etc.
Memorex has a habit of switching manufacturers of their media. The manufacturer for Memorex -R at this time is CMC Mag. They produce very poor quality media. So at present time it is on the do not use list. Some may work but its a 50 50 chance of failure. Jerry
