DVD Shrink is a free DVD compressor to backup your DVDs.
You can use this free DVD backup tool in conjunction with DVD burning software of your choice, to make a backup copy of any DVD.
I have used this free DVD backup tool for some time now, and it is EXCELLENT !!
Normally you can't backup a DVD because it is too large to put on to an ordinary DVD-R disc.
Also nowadays Nero or other burning software won't work because the discs are copyright protected.
DVD Shrink overcomes this and allows you to copy direct to disc or (which I prefer) to copy to your Hard Drive.
Also you can, if you wish, just copy the Main movie and not all the extra bits and pieces you get.
Once again, a SUPERB FREE PROGRAM !!
