1.	Solve : DVD Region - Can only be changed up to 4x ... WHY the limitation??
Answer» Removed a DVD/CD-RW drive from my system which initially had 2 optical DRIVES to install the older DVD/CD-RW drive into a Pentium 4 I have that I WANT to install Linux Mint 14 on and the ISO's are greater than 700MB so it needed this DVD support. I booted my MAIN system up WINDOWS 7 Home Premium after removal of this slave optical drive and decided to look into properties to make sure everything looked ok after its removal. And when looking through tabs I came to this ability to change the region that the DVD-RAM drive operates as, and the caution message with the fact that this can ONLY BE CHANGED UP TO 4X struck me as very odd... ANYONE know why the drive can only be changed 4x in Optical Drive Properties? [year+ old attachment deleted by admin]
