"Please explain the DRM code controversy?"
Sony / BMG's newer CDs install a program that prevents you from making more than 3 copies of a music CD.
The problem is that 1) the user doesn't know it, 2) the end user license agreement (ELUA) when found it horrible, and 3) Sony uses "cloaking" software that is easily hacked.
Cloaking - that's a practice by where a program can be run on your PC w/o you ever finding out unless you use special tools (rootkit).
The cloaking software that Sony is using can be used to hide ANY program, including viruses and spyware. Soooo... the latest viruses are now looking for this utility so that they can hide from you and your antivirus programs!
please add 4) may cause some computer to crash causing a system32 error.
i've not had this happen to me but i did have to repair one computer so far that crashed after loading velvet revolver cd into her computer.

it was an easy fix for me but it costed her $50 for me to restore her system32 files. i'm not sure if this is the same stuff but it can cause problems.
WINDOWS HINT: hold down the shift button when placing a music CD into your computer. leave the button held down for about 60 seconds until your computer stop trying to load it. this disables the auto run. after that you should be able to run your regular buring/backup software.
