Hi there for a start if your hardware mainly reader/burner is up to spec and you follow our tut's it should be plain saling. The main apps to look out for are Alcohol 120, Blindwrite,RecordNowMax and Nero. Some disc needs to be read or burnt at lower speeds.
Copying from disc to disc well since most have some from of protection on them you will not get a working backup of your disc from some of the apps out there plus it better to copy to hdd...
