Not sure how to burn a dvd to another dvd?
Here is a program I use if I want to copy a movie from one dvd to another. It really works excellent and is easy to use.
Here is how you do it:
Go to the following website and download and install it.
Then open the program, insert your dvd into your cd rom and click on the open disc button
After it has opened the disk click on back up button and wait for it to back up (this can take quite a while - probably half hour depending on which movie you are downloading.
When it is finished backing up your files it will ask you to insert a disk and the you insert the clean dvd and it will burn it to that dvd.
Also you will not be able to use dvdshrink if any of your dvd's are scratched.
If you are copying a movie, you will need a program like 1Click DVD. www.1clickdvdcopy.com If the DVD just has data or pictures on it you can do a couple things. Use a disk copy program like Roxio, or create a folder on your desktop, use explorer to view the contents of your DVD and copy all the files into the folder on your desktop. Then insert a new DVD into your drive, select all the files in the folder on your desktop right click on them and choose "Copy to DVD"
