Is there any way that i can play a Different region DVD on my DVD player(region 4)? and if it is possible, How do i do it¿
When you rip/copy the "region4" DVD to your harddrive with DVDshrink (or DVDdecrypter), it should remove the "region" specification so that's it's entirely "region free." You may have to specify what region the DVD is coming from (in your case region 4), before it starts copying. Then burn a blank DVD from your hard drive with Nero (or some other burning program)... There ya' go, a "region free" disc. So, all you need is "DVDshrink"[free/shareware] and "Nero Burning ROM"[trial version is free for 2 weeks, I think]... Both of which you can download from afterdawn.
AnyDVD will also allow you to decrypt the DVD and remove all region info. Use CloneDVD to copy the DVD then. Guides for this in my signiture below
