Its fairly straight forward... ..simply throw them onto a raging fire.</p> </p> you asked for that!</p>
Where to start This is nowhere near as straightforward as burning CD's. Unfortunately most commercial DVD's are dual-layer (which hold up to 9GB of data) whereas most DVDR's are single layer (only 4.7GB). This means you need to shrink the content to fit. There are many freeware solutions for this but they take a bit of getting your head round. If I were you I would get the trial of CloneDVD here http://www.slysoft.com/en/download.html For some copy protected titles you also need AnyDVD. These cost money but are the closest you can get to "simple disc-to-disc" copying.
Get DVD Shrink to compress and remove encryption. Yer can then burn the output files in Nero or summert else.
If you wish to use freeware There are some good guides on this site: http://www.doom9.org This is an entirely objective recommendation and nothing to do with me being an administrator of said site (chinny)
